12/24/2020 Give Mac App Priorioty
Priority is your collection of invites to make the moments you live for. Sipping coffees on the house. Strolling past queues at sold-out venues. Getting first eyes on fashion collections. Or getting first dibs on gig tickets. And it’s all yours, just for being on O2. Launch the app and you’ll see t. The default priority is zero, positive values are 'nicer' (that is lower priority) and negative values are 'less nice' (higher priority). Looks like Mac OS runs from +10 to -10. Use renice to change the priority of a process already running (from the renice man page on 10.5). Priority is your collection of invites to make the moments you live for.

Launch the app and you’ll see t. How to set bandwidth priority using task manager? You can easily limit the bandwidth priority for an application using the task manager. Open the task manager and under the Details tab, you will see all the apps running. Now right-click on any app and hover over Set priority and now you can choose any of the realtime, high, normal, etc. How to Give System Permissions for Apps on MacOS Catalina. Starting with macOS 10.14 Mojave, Apple has introduced a new security feature that ensures third-party applications work safely with your data.
I use Handbrake to convert video files all the time. It works great. Unfortunately, converting videos takes a lot of computer power, and my trust Macbook Pro is getting a little old (nearly 3 years since I bought it — that’s like middle aged in computer years). That means that when I try to convert a video and simultaneously work on other stuff, things get a little choppy, and sometimes downright unusable.
Luckily, OSX has a built-in command in Terminal that lets you reset an app’s priority. It’s called the “renice” command, and here’s a thread all about it. While I’m learning to use Terminal, I still find a GUI much easier. Unfortunately, several of the apps featuring a GUI won’t run on OSX Lion. However, I found an Applescript in this thread that seems to do the trick!
I changed a few things and packaged it up as both an Applescript (for those of you that might want to tweak it more), and an application (for those of you that want to just click and have it work). Seems to be working — I turned Handbrake down to 10, and I’m suddenly able to get work done in the meantime. My understanding is that this will make the conversion slower while I’m working on my comp, but that when things quiet down, it will go back to full throttle using Handbrake, since there are no active higher priority jobs. Note the range from -20 to 20, where positive numbers will decrease the priority and negative numbers increase the priority, with the default priority right in the middle at 0.

[edit]Introduction
Be using a build NO OLDER than r32170 before proceeding!
Quality of Service (QoS) is a method to guarantee a bandwidth relationship between individual applications or protocols. This is very handy when you max out your connection so that you can allow for each application to have some bandwidth and so that no single application can take down the internet connection. This allows, for example, a full speed download via FTP without causing jittering on a VOIP chat. The FTP will slow down slightly as bandwidth is needed for the VOIP, provided VOIP was given greater priority.
Please note, as of 336XX, if QoS is enabled, SFE (Shortcut Forwarding Engine) is disabled, even if it shows up as enabled in the GUI, it is disabled.
If you plan on using QoS, please read Priorities explained and Precedence before going any farther.
[edit]Priorities explained
Bandwidth is allocated based on the following 'minimum to maximum' percentages of downlink and uplink values for each class as of current builds:
What this means is that if you have 10,000kbit of uplink traffic, 'Standard' class traffic can be reduced and de-prioritized to 15% or 1,500kbit when a concurrent express or higher priority service requires the down/uplink pipe at the same time.
Check which priorities are used with the command below:
Then scroll down to the Chain SVQOS_SVCS section.
Give Mac App Priority Login[edit]TCP Packet Priority
Builds before r21061 will not have this option. Update your build if you dont have it, stay up to date.
Prioritize small TCP-packets with the following flags: ACK/SYN/FIN/RST
For detailed info on what these packets do see: http://en.wikipedia.org/wiki/Transmission_Control_Protocol#TCP_segment_structure
It is highly recommended to have at least, SYN, FIN & RST checked, OR, none at all. ACK can go both ways as P2P intensive applications such as uTorrent etc involve a lot of ACKs, so theoretically prioritizing ACKs means you 'prioritized P2P' though that is not entirely' accurate. Read up & do your own testing to find out whats best for your network. If you do not do large amounts of P2P activity on your network or none at all, then enable ACK prioritization.
[edit]Precedence
With all these ways of marking traffic its easy to get confused about how seemingly contradictory requirements are resolved. For example, what happens if you have an IP rule setting IP 192.168.1.2 to priority 'maximum' and have a MAC rule setting AA:BB:CC:DD:EE:FF to priority 'bulk'?
The order the precedence is as follows:
NOTE: Ethernet Port Priority only works on old 802.11g only models with ADMtek switch chips. If you don't have ethernet port priority listed, your router does not support it. Ethernet port priority is different than interface priority.
NOTE: Services can be used at the same time as netmask or MAC, such as limiting 192.168.1.2 to 6 Mbps down & 512 Kbps up while having http set to express, that device will have http packets prioritized within it's allocated bandwidth limit. This only applies to builds r21061 & newer
For netmask, the IP address entries are applied in the order that they appear in your netmask table. Only the first match applies. Example, if you have an entry marking 192.168.1.10/32 as bulk, followed by an entry ABOVE IT, marking 192.168.1.0/24 (all 192.168.1.X) as premium, the traffic from 192.168.1.10 would be marked bulk because it was the first match.
For services, The services entries are applied in the order that they appear in your services tables going from bottom to top. Again, only the first match will apply.
[edit]Initial Setup
Give Mac App Priority AppIt probably bugs you to set less than 100% of your available bandwidth in these fields but this is required. There will be a bottleneck somewhere in the system and QoS can only work if the bottleneck is in your router where it has control. The goal is to force the bottleneck to be in your router as opposed to some random location out on the wire over which you have no control. Some ISP's even have bursting ('powerboost') which will temporarily give you extra bandwidth when you first start using your connection but will later throttle down to a sustained rate. Fortunately there is usually a minimum level that you receive on a consistent basis and you must set your QoS limits below this minimum. The problem is finding this minimum and you may have to repeat speed tests many times before determining it. For this reason start with 80% of your measured speed and try things for a couple of days. If the performance is acceptable you can start to inch your levels up. If you go even 2% higher than you should be, your QoS will totally stop working (just too high) or randomly stop working (when your ISP node/DSLAM is slow aka saturated). This can lead to a lot of confusion on your part so get it working first by conservatively setting these speeds and then optimize later. [edit]Prioritizing by Application (Skype, Http) or Port Range (P2P)
If you wish to add more than one priority then use the 'Add' button to create more entries.
[edit]Prioritizing by Interface
Select your preferred interference, click add, then select the speed or priority you want. You can also limit ethernet ports this way as well (ethX or vlanX). Any limits or priorities set are shared for that interface regardless how many clients are connected to it. Excellent for running a guest network/hotspot on eg, ath1.1, applying QoS on the entire interface makes it impossible for a greedy user to bypass it by MAC cloning, changing IPs etc, short of connecting to a different interface. The same interface can also be entered multiple times with different speed limits or priorities for different services, example, ath0 512/512 with ssl & ath0 0/1024 with http would mean ssl traffic on ath0 is limited to 512kbps down & up, http is unlimited on down (up to global limits is used) & limited to 1024 (1mbps) on up, remaining entered services are not limited (up to global limits for both directions).
[edit]Prioritizing by Netmask (IP address)
These are entered in CIDR notation including the network prefix.
For example, to specify a single IP address enter xxx.xxx.xxx.xxx/32. Be careful to enter netmask as /32 because leaving it /0 means ALL IPs!.
The netmask is the number of bits of the IP address to match. For example, the entry 192.168.1.0/24 matches 192.168.1.x addresses. An entry of 192.168.0.0/16 matches 192.168.x.x addresses. If you're unsure of how to create CIDR subnet masks and what they mean, then use a subnet calculator.
After you have filled it out, press 'add' next to it. If you want to add multiple entries (make sure to have order correct!) click 'save' before entering in another so any previous changes don't get deleted, only click 'apply' when you want to start testing your current changes displayed.
Give Mac App Priority Email[edit]Prioritizing by MAC Address
In the case you want to prioritize traffic from a particular device without a static IP address on your LAN, you can prioritize by MAC Address. Enter the MAC Address of the device and press 'Add' next to it.
[edit]How Do You Check What QoS Priorities Were Applied
The DDWRT web UI doesn't display any live traffic. Short of doing a practical test, you can get your hands dirty by checking the conntrack entries via telnet or ssh access in the router. When you're logged in run:
Then scroll down to the Chain SVQOS_SVCS section.
With the above iptables mangle command you can see the inbound/outbound chains, entered IPs/MACs/services & whats being matched where.
It will list out all currently open connection and protocol that is currently being routed by the router. This is what it would look like:
What you'll be interested to look at will be the first set of source and destination IP, including the port numbers. Next the presence of l7proto and the 'mark' field. The entries indicate the current live connection QoS priority applied on them based on the 'mark' field. The 'mark' values corresponds to the following:
Give Mac App Priority PasswordYou may see 'mark=0' for some l7proto service even though they are in configured in the list of QoS rules. This may mean that the layer 7 pattern matching system didn't match a new or changed header for that protocol. Custom service on port matches will usually take care of these. [edit]Time Based QoS
Iphone app on mac to export photos. As described in this thread you can use CRON jobs to enable/disable QoS. This is just a simplistic approach but more complex things could be done if you put your mind to it. These commands will enable HTB QoS on the WAN port from 5PM to 1AM but you will still need to configure everything else in the GUI. If you want to use LAN&WLAN then change '`get_wanface`' to 'imq1'. To change the times, see the CRON page for information.
If you use HFSC then you would do something like this instead.
As described in this thread you can also set different rates at different times by doing something like this which changes the HTB rates.
Edit: This will cause trouble on current firmware releases greater than r21061. Mac interior design apps. Use the predefined service handler to stop/start QoS instead. Even if needed, use imq1 instead of br0 for internal traffic shaping.
If you need to alter down/up rates edit the nvram variables before restarting wshaper
