tzava-ro Posted August 2, 2014 Report Share Posted August 2, 2014 Hi guys . I kept searching the web to no avail so i created an account here to ask : I have a Gigabit line ( 1000 Mbps ) Internet connection.The PC is :i7-479016Gb RAMDisks are sepparated like this 2x WD raptor ( 10K rpm ) 16k Stripe for the os2x Seagate Constellation 500GB - 32K Stripe for torrents. I get disk overloaded when starting a bigger ( > 10 Gb torrent ), after ~1 min ( allocation is completed ) speed goes up to 60-70Mb/sec and holds for another 2-3 min. The cache is then filled, disk overloaded appears, torrent goes to 20-30k/sec.. I have set pre-allocation - off I even tried this : 5x 72gb IBM SAS 10k Rpm disks in 1 stripe on a LSI Megaraid Pciex8 adapter with 512Mb Cache. SAME PROBLEM.. ( This setup has a small-file 4k sustained write of 275mb/sec ( 20gb of files )) i tried all cache settings ( now on default settings ) Got any ideas ? Thank you.

Kitsoran Posted August 2, 2014 Report Share Posted August 2, 2014 When DO occurs, do you see any writes occurring or does it just get stuck? For me it just got stuck Link to comment Share on other sites More sharing options...
tzava-ro Posted August 2, 2014 Author Report Share Posted August 2, 2014 I do see writes, but only 20-30Mbps max .I forgot : Utorrent - 3.4.2 build 32126 Win 8.1 64bit Link to comment Share on other sites More sharing options...
rafi Posted August 3, 2014 Report Share Posted August 3, 2014 With my settings file (Upload limit adjusted) , you should reach 12-14Mbps. I don't expect much more with the current release. Link to comment Share on other sites More sharing options...
tzava-ro Posted November 19, 2014 Author Report Share Posted November 19, 2014 So i found a way that "works" : Set DL limit to 15Mb/sec. This will cause the freeze but it will be only for a short time ( i guess until all files are "initialized" on disk ). This is also dependent on the size i want to download. Nasty behavior : when disk freeze happens, everything freezes. Os, even chrome ( has nothing to do with the torrent disk / internet usage ). Task manager says : disk C usage 1%, disk D ( torrent ) 100%, CPU 10-12%, and ram ~12GB free. As a solution ( not really ): change priority to lowest possible on utorrent. This will not stop this behaviour, but will make it less visible. Are there any kind of fixes for this ? or i`ll just have to live with it ? Thanx.

tzava-ro Posted March 5, 2015 Author Report Share Posted March 5, 2015 Ok guys .. found a solution ( might be only for me, i`ll post it anyway ) Windows 10 Preview. Same utorrent as above, same disks. 25-30Mbps sustained, no disk overloaded ( 56Gb torrent ). Disk usage spikes every second to 100% ( for the torrent drive ), but no slowdown for the system, browsing and even gaming works perfectly Link to comment Share on other sites More sharing options...
walter.vlatko Posted March 5, 2015 Report Share Posted March 5, 2015 Try diskio.sparse_files true. You can also download the latest version from utorrrent website (update in utorrent won't work I don't know why). Link to comment Share on other sites More sharing options...
rafi Posted March 5, 2015 Report Share Posted March 5, 2015 25-30M is VERY nice! I'd say it is very close to your HD capability. Is it also for multi -files torrents or only single file? For me performance of multiple-files torrent is much worse than single file. Link to comment Share on other sites More sharing options...
tzava-ro Posted March 8, 2015 Author Report Share Posted March 8, 2015 @ rafi - multi-file torrents are slower in the beginning. they go at around 10-12mb/s for a few minutes ( guess it`s the allocation, although in task manager they are at 30-40% usage ). The torrent "disk" is a stripe ( 2x 250gb HP WestenDigital RE ). They can write with ~150mb/s. Now if you mean a lot of small files ( example 1gb / 2500 files ) yes that will go slower. But for 15gb / 120 rar files, no difference vs 1 file. Link to comment Share on other sites More sharing options...
rafi Posted March 8, 2015 Report Share Posted March 8, 2015 Hmm.. I wonder if Win 10 has some secret ingredient that makes it faster... By multi-files I meant even a few 5-6 files, which makes the write access - unaligned (no 16k piece boundary), thus - much slower. I get only 12-14MB/s for a multi-files torrent, while I can reach even 40MB/s (on my local LAN) with a single file torrent... Link to comment Share on other sites More sharing options...
