chaosblade Posted October 12, 2005 Report Share Posted October 12, 2005 Exactly. Maybe there's a tool somewhere on windows that lets you control or see it in action, The management console or something along the lines. Then again, it might be an internal system service that you wont have any idea or info about. Link to comment Share on other sites More sharing options...
ludde Posted October 12, 2005 Report Share Posted October 12, 2005 What does your system cache field in the Task Manager say? Windows probably uses your RAM for file caching, it's not uTorrent. Link to comment Share on other sites More sharing options...
rjsoz Posted October 12, 2005 Report Share Posted October 12, 2005 Sorry if you already know all of this...In task manager, you can select additional columns to display the other memory statistics for each process. Add the following columns: "Virtual Memory Size" and the two below it "Paged Pool" and "Non Paged Pool".Now sort each of those columns and have a look at what's largest. Also check the "System Cache" size on the "Performance" tab - that's the disk cache...At the moment, I've only got one torrent running, with only a handful of peers, and utorrent is using 1.7mb of VM and about 2.5mb of physical memory - my disk cache is sitting at 170mb and rising - and my available is dropping at a matching rate. (disk cache now at 180mb) Don't stress about your cache and available memory - Windows handles it all so you don't run out - provided it's the System Cache that's taking up the memory I love this little app!

tozz Posted October 12, 2005 Report Share Posted October 12, 2005 Problem is, Windows handles this very badly, and if the application relies on it the system gets heavy performance hits once it runs out.It's not system cache that's taking up the memory, it's keeping steady at 500mb while available Physical Memory goes from 400 to 600 in a second once uTorrent is closed or all torrents are stopped.In the end, the memory usage is directly related to uTorrent, the behaviour can be repeated under any circumstance.

costa Posted October 12, 2005 Report Share Posted October 12, 2005 tozz: exactly what i'm talking about - overall memory usage is just not changing that much. utorrent running or not - nothing that much big happens. utorrent takes its 5 or so megabytes and nothing more. come on, i know where to look in task manager and i'm saying you - no problems. the program worked for two days and everything runs just lovely. the amount of physical memory is steady, swapp almost not used... man, this app rocks!do you guys all have sp2 and latest windows upgrades? maybe somewhere here lies the problem. on pure sp1 (ok, one thing upgraded - windows installer) everything seems to be all right.

chaosblade Posted October 12, 2005 Report Share Posted October 12, 2005 when you do that, check the task manager's performance tab, 'System Cache'. If that drops, it means windows' disk caching is to blame. Link to comment Share on other sites More sharing options...
Guillaume Posted October 13, 2005 Report Share Posted October 13, 2005 I checked that, system cache does NOT change when closing µTorrent. Mem free was 87MB when µTorrent was running, after closing it, I got 329MB free mem, system cache was ~371500kB before and after closing µTorrent.

rjsoz Posted October 13, 2005 Report Share Posted October 13, 2005 Start performance monitor, add all of the counters under Process and select the utorrent process... you'll see if any of those counters are huge... let us know what they are.

Undesirable Posted October 13, 2005 Report Share Posted October 13, 2005 Confirmed. I knew there was a reason why Azureus sucked up so much memory. It seems that µTorrent simply hides the exact memory usage in order to look superior. I find it to be an amazing coincidence that Azureus ends up using around 200 megabytes; thought it was too good to be true that µTorrent cut that down 50x.

Guillaume Posted October 13, 2005 Report Share Posted October 13, 2005 Start performance monitor, add all of the counters under Process and select the utorrent process... you'll see if any of those counters are huge... let us know what they are.Nothing to be seen under the utorrent.exe process that adds up the large memory use. But don't conclude now that it's not µTorrent that causes it, because it's the only program that can cause this, since lots of people can confirm it. If it's crappy Windows caching, then µTorrent should work around this, since it's the only program that's got issues with it. While testing I checked 'Connect to peers slower' a couple of times, which turns out to have no desired effect on the memory usage. Link to comment Share on other sites More sharing options...

moPP Posted October 13, 2005 Report Share Posted October 13, 2005 I can confirm this as well.It frees up over 300 mb physical ram (system cache stays about the same) as soon as I shut down uTorrent. However, I don't notice any performance hit whatsoever.Windows Server 2003 Standard SP11024 mb ram Link to comment Share on other sites More sharing options...

Aeon17x Posted October 13, 2005 Report Share Posted October 13, 2005 The question is, do you see a performance hit? Because for all we know it's just Windows panicking and screaming when it saw uTorrent consuming too little memory. >_> Link to comment Share on other sites More sharing options...
Guillaume Posted October 13, 2005 Report Share Posted October 13, 2005 I do, starting up programs, opening up multiple tabs in Firefox, it all takes a lot more time and more harddisk activity then when µTorrent is closed or if I'm running another torrent client, like BitComet.[edit]I have to reconsider the previous statement after being able to start up a virtual machine (Virtual PC) that takes up 224MB Ram, while free ram was indicator was only at 88MB. Normally Virtual PC shows an error message when free RAM < 230MB when starting such a virtual machine...However, with other programs it does seem to take more harddisk activity somehow to start them and work with them.

OCedHrt Posted October 13, 2005 Report Share Posted October 13, 2005 Downloading one, seeding another. One is 8 gb, one is 14 mb. All seems fine for me.The private bytes shown here are probably the "hidden" memory that is leaking. Mine shows about 5 mb but a clean start of utorrent is around ~2MB so it may be growing. There isn't much else that Process Explorer provides. Link to comment Share on other sites More sharing options...
Niceguy Posted October 13, 2005 Report Share Posted October 13, 2005 hmm had the same results on win2k pro. started a torrent with alot of seeds and peers, the physical memory just started to decrease rapidly until it hit rock bottom and then it started to chew on the systemcache. so I stopped the torrent (not closing utorrent), and all the physical memory was instantly returned...

chaosblade Posted October 13, 2005 Report Share Posted October 13, 2005 It's really odd, as i notice no hit what so ever. Windows XP SP2 without the TCPIP patch. 512MB of DDR and page file set to 768MB exactly on my C: drive. Link to comment Share on other sites More sharing options...
True Posted October 13, 2005 Report Share Posted October 13, 2005 On the Windows box I use this on, I noticed heavily decreased system performance, but I thought it was just Windows (my Gentoo boxes certainly doesn't do any of that). I am not there to verify right now whether uTorrent is the problem, but that is the only major change I have made recently.It is still on 1.1.3 though - don't know if this was introduced with 1.1.4 or if it affects that version as well.
