digicat Posted May 8, 2008 Report Share Posted May 8, 2008 I have a seedbox on a 100mb line with windows 2003 web edition. I have 2 gb of ram with the disk cache set at 1gb so i dont have disk overload, and i dont. My problem is that every time I start a new large torrent download , say 20gb or so starts, all my other torrents that are uploading at normal speeds like 2-3mb all stall to a crawl at literly 2-3 k/s. It does pick bak up after 15 or so minutes but i loose valuable upload time. I do have bout 7-10 torrents running at all time. Is there any setting i can use to help prevent this. An help would be appreciated. Title says bogs down upload on new torrents i meant existing Link to comment Share on other sites More sharing options...
jewelisheaven Posted May 8, 2008 Report Share Posted May 8, 2008 If you currently are, don't pre-allocate? Sparse files and disabling the disk-hungry activities in the Disk Cache pane should be enough to keep your cache highly used. Also, are you using compact allocation?

digicat Posted May 8, 2008 Author Report Share Posted May 8, 2008 thanks again jh for answering another post. to be honest with you i am not sure what compact allocation is, nor pre-allocate. here is my disk cache settingshttp://img392.imageshack.us/img392/4272/49146939bu0.jpg Link to comment Share on other sites More sharing options...
jewelisheaven Posted May 8, 2008 Report Share Posted May 8, 2008 Pre-allocate is under Downloads.You may want to turn off "write out finished pieces immediately". Additionally this may be due to something about windows cache. In 1.8 there is an option below "increase cache size when thrashing" to disable windows cache for reads and writes. You may want to try it out in a self-contained http://utorrent.com/faq.php#How_can_I_share_my_torrents_between_user_profiles.3F to test. Link to comment Share on other sites More sharing options...
Firon Posted May 8, 2008 Report Share Posted May 8, 2008 The reason that happens is because it has to allocate the files to disk. This takes time, and will take even longer if the disk is being used by other torrents.You can turn on sparse files, but fragmentation can increase.

hermanm Posted May 8, 2008 Report Share Posted May 8, 2008 Firon, is fragmentation detrimental to disk performance? I defrag out of habit, but a part of me makes me wonder if it is worth the trouble since torrent piece disk activity seems random anyway. Link to comment Share on other sites More sharing options...

jewelisheaven Posted May 9, 2008 Report Share Posted May 9, 2008 Fragmentation is only really a problem when you're < 20% disk free. Windows does all the allocation behind the scenes. If however you decide to start downloading really large individual files without defragging your fragmentation will increase by magnitudes. If you don't want to deal with a full defrag, you can also check out "Contig" by sysinternals. It allows... per-file defragmentation. Though TBQH I only use it for pagefile touchups when I reinstall windows. Link to comment Share on other sites More sharing options...
Firon Posted May 9, 2008 Report Share Posted May 9, 2008 No, Windows is really stupid and will fragment at much higher amounts of free space with sparse files. Link to comment Share on other sites More sharing options...
jewelisheaven Posted May 9, 2008 Report Share Posted May 9, 2008 How much higher? I've got an average of 1.12 fragments per file on my 80% full 120 gig partition. Link to comment Share on other sites More sharing options...
Firon Posted May 9, 2008 Report Share Posted May 9, 2008 download more than one torrent at once and you'll see what I mean. I had some files with almost as many fragments as there were MBs in the file, lol Link to comment Share on other sites More sharing options...
