fatila Posted October 23, 2008 Report Share Posted October 23, 2008 Hi,I've just run into this issue with a large torrent with files within ranging from a few hundred kb to 40GB. The client will download for a while, then speed will drop to 10k until maybe 20-30 minutes later when it starts back to normal speed again and the pattern continues. I tried increasing my disk cache in memory manually to 1GB and this helped until it reached that size then the problems resumed. The drive is a new WD 1TB greenpower which I've seen hit over 80MB/s. This is very frustrating behaviour, any ideas as to what the problem might be?Client is 1.8.1, OS server 2008 32bit. Link to comment Share on other sites More sharing options...

Ultima Posted October 23, 2008 Report Share Posted October 23, 2008 Don't write pieces out immediately. Don't remove old blocks from the read cache. You may want to disable reduction of memory when cache is not in use. Link to comment Share on other sites More sharing options...
fatila Posted October 23, 2008 Author Report Share Posted October 23, 2008 That might have done the trick, thanks. Coincidently torrent speeds dropped right after I made change so was hard to tell, but now I have 2 going near line capacity. Link to comment Share on other sites More sharing options...
fatila Posted January 2, 2011 Author Report Share Posted January 2, 2011 Ok two years later and this issue persists, I have been ignoring it, just letting the disk stop overloading but I really need to fix this now.If I turn off write caching the disk stops overloading, but then utorrent allocates about 1.9GB ram and then comes to a complete halt. If I enable write caching then after downloading a certain amount (seems to be 2GB odd again) the speed will drop to sub 10kbps and 'disk overloaded' will appear. There must be something I can do to stop this.I had a clean install of 2.2 recently but have changed he settings in line with the suggested steps above. MY system is now server 2008 R2 64bit and the main disk is a 2TB wd green. Link to comment Share on other sites More sharing options...
Dvvarf Posted January 2, 2011 Report Share Posted January 2, 2011 fatila, I had the same problem a while ago. Failed to solve it properly, but to get your torrents downloaded you could try this: delete the downloaded data completely and remove the torrent from utorrent, then add it again. Worked in my case for a few times (on two different machines with win2k3 and win2k8). I guess it has something to do with preallocation. Link to comment Share on other sites More sharing options...
