rolls Posted October 14, 2009 Report Share Posted October 14, 2009 I constantly upload about 12 files (they vary) at 220kb/s Now I have played with the caching settings and found slight gain going from 32mb read cache to 128mb read cache (I have plenty of ram)I am averaging about 36% hit ratio on the cache and about 200-300B/s read according to resource monitor.Now with 32mb cache I get about 300-400B/s read.I have 'disable windows caching of disk reads' unticked, would this likely improve my performance even further?I would happily set a 2gig cache (overnight when computer is not used) if it increased the hit ratio to 75%. Is there any way to do this?Should I disable the windows caching or leave it enabled? My ultimate goal is to minimise hard drive reads to keep the noise down as the PC is in my room, also I'd like improve its life Link to comment Share on other sites More sharing options...
Ultima Posted October 14, 2009 Report Share Posted October 14, 2009 The user manual's description of the Disk Cache options tell you exactly which options decrease disk access. Less frequent disk access won't improve it's life by any noticeable amount -- it's disk spinup/spindown that causes more drive wear and tear.

rolls Posted October 17, 2009 Author Report Share Posted October 17, 2009 I know which ones decrease it but to what extent, is adding 512mb of ram to the cache going to help at all? Link to comment Share on other sites More sharing options...
Ultima Posted October 17, 2009 Report Share Posted October 17, 2009 There's no absolute answer. It depends on how fast your connection is -- your first post is rather imprecise about units.At any rate, if your connection is rated in the mbit/s for both upload and download, then cache sizes in the hundreds may be helpful in maintaining speed and preventing disk overload. Just keep in mind that there is a diminishing rate of return as you increase the cache size. As well, as far as I remember, µTorrent does not handle cache sizes over 1 GB well, so don't set anything above that. Link to comment Share on other sites More sharing options...
Switeck Posted October 17, 2009 Report Share Posted October 17, 2009 uTorrent is a 32 bit application, so both it, its variable space, AND its ram cache cannot total over 2 GB ram.I've had the ram cache as high as 1700 MB before without problems, but I was running only about 5 torrents.

Ultima Posted October 17, 2009 Report Share Posted October 17, 2009 Yeah, I know what the theoretical limits for 32-bit apps are, but I remember some users experiencing crashes when the cache size went above 1 GB. Maybe it was fixed -- don't know.Scratch that, after some searching, it was indeed crashing over 2GB (and not 1GB) after all. Mixed up the numbers.

rolls Posted November 10, 2009 Author Report Share Posted November 10, 2009 Ok thanks guys, I am currently seeding a 11gig torrent only and wanted to minimise disk access so I have temporarily increased the cache size to 1gig, will see how much it decreases the disk accessing the data.

Switeck Posted November 13, 2009 Report Share Posted November 13, 2009 Make sure to DISABLE the cache settings that cause the cache to make itself smaller. Link to comment Share on other sites More sharing options...
