Iwo Posted March 10, 2008 Report Share Posted March 10, 2008 It will be nice when user could set 1) priority of app 2) affinity of app.Both of course can be set by task manager. But I mean setting, which is always applied - by uTorrent itself. No need to use external apps.BENEFITSAD1) Sometimes we run CPU-Intensive apps, like compressing ones (7-zip, winrar) or games, but we want uTorrent to work at full speed. Setting to HIGH or Above Normal priority could help. Realtime should not be allowed (shortest way to crash system).AD2) Most apps are single-threaded. Probably uTorrent too. There is common tweak to boost speed of e.g. single threaded games by setting affinity of game to CPU1 (which means second core or second CPU) and systems apps to CPU0. For non-native quad-core processors (2x2 not 4x1) like Intel Core Quad, setting CPU2 or 3 for one app and CPU 0 or 1 for second also leads to not sharing L2 cache.I, for example, set game to CPU1 and uTorrent, eMule, taskmgr, Skype, firefox, explorer (it is quite wise to close explorer), IM app and others to CPU0. Counting on OS auto setting of affinity (CPU0 _and_ CPU1 and CPUX) is not so good. Two apps working at 100% on dual core processor work faster with fixed affinity than with OS-auto-on-the-fly-menaged. There was optimized BOINC client which set all apps to fixed affinity.

jewelisheaven Posted March 10, 2008 Report Share Posted March 10, 2008 Until multi core CPUs start phasing out single core ones, WTM is just an easy a place to set it up IMO. Link to comment Share on other sites More sharing options...
Iwo Posted March 10, 2008 Author Report Share Posted March 10, 2008 >70% of people I know have two+ core processors or P4 HT. Only 2 persons have Athlon XP or Athlon 64. All new computers they buy, are with 2Cores, one with 4. With WTM I need to set this setting each time - with option in uTorrent, this setting will be aplied automatically each time.

DreadWingKnight Posted March 10, 2008 Report Share Posted March 10, 2008 Actually, uTorrent is multithreaded.Although no one task is spread across multiple threads, each task (disk, network, new connections, interface) has a separate thread. Affinity would actually potentially degrade performance of the system by clumping all the threads on the one processor core.Your process priority suggestion still has some merit, but affinity forcing a multithreaded application is just asking for trouble.

Iwo Posted March 11, 2008 Author Report Share Posted March 11, 2008 I assumed that uTorrent is single threaded. If it is properly multi-threaded, then affinity setting is useless indeed. So, just add app priority setting Link to comment Share on other sites More sharing options...

Iwo Posted March 26, 2008 Author Report Share Posted March 26, 2008 So, If I have one, single-core processor, I force encryption for both incoming and outgoing connections, I have >100 connections and >5 torrents working - then I start CPU-hungry app like some games - both uTorrent and this app are in normal priority - do you think, that there will not be any slowdowns for uTorrent ?BTW. Any idea, why eMule HAS option to select self priority ? Link to comment Share on other sites More sharing options...
jewelisheaven Posted March 26, 2008 Report Share Posted March 26, 2008 If your game is using the CPU for rendering you have a larger problem. Encryption between peers adds negligible overhead CPU-wise, it does add some bandwidth. uTorrent would react just as similarly as Explorer would in that case, nothing more or less negative of an impact no matter what other software you're running.emule is a separate program and as such why do you think the developers for uT would know the philosophy behind another application's included features?

Firon Posted March 27, 2008 Report Share Posted March 27, 2008 My ut is pretty much unaffected when I do other stuff. Even played Crysis while torrenting. Link to comment Share on other sites More sharing options...
olmari Posted March 28, 2008 Report Share Posted March 28, 2008 Well... Automatic priority at startup I can see the benefits in itself, but when starting your "other CPU-intensive" task like 7zip, shouldn't 7-zip have an similar option too, to get it automatically below normal Anyways, I'd like to see priority option in every program...

John Peterson Posted February 7, 2012 Report Share Posted February 7, 2012 Eh. Kind of pointless.Why is it pointless? There is a I/O priority setting.I want uT to run at idle priority to not disturb other applications.A program like this that often run in the background should have a priority setting since users will often want to run it at low priority.Thanks!

xtf Posted February 7, 2012 Report Share Posted February 7, 2012 Well... Automatic priority at startup I can see the benefits in itself, but when starting your "other CPU-intensive" task like 7zip, shouldn't 7-zip have an similar option too, to get it automatically below normal uT is more likely to run then 7z. You don't run 7z 24/7 Anyways, I'd like to see priority option in every program...Nah, it'd make more sense to have the OS take care of that.My ut is pretty much unaffected when I do other stuff. Even played Crysis while torrenting.Good for you, but that doesn't mean other people can't be affected. Link to comment Share on other sites More sharing options...
Firon Posted February 7, 2012 Report Share Posted February 7, 2012 µTorrent is multithreaded. Processor affinity is a stupid setting. The client sets itself to low priority. This is a 4 year old thread. Link to comment Share on other sites More sharing options...
