SSDs do about the the same speed for sequential or random. Non-array spinning drives do better, maybe getting 10MBytes/sec. My spinning RAID6 array does 1600MBytes/sec for sequential transfers, but plummets to 2.5MBytes/sec for random transfers. This is the worst possible load for spinning (older mechanical) drives. Check Disable Windows caching of disk reads.īy default, bittorrent transfers are random pieces of the file(s).Check Disable Windows caching of disk writes.Check Increase automatic when thrashing.Check Turn off read caching if upload slow.Check Write out finished pieces immediately.Check Override automatic cache size and enter 1024.If you have only one disk and it's spinning, set them false and have Pre-allocate checked. diskio.no_zero doesn't work as you can't run uTorrent as Admin without causing other issuesįor the last 2, use a SSD, make sure Pre-allocate all files is unchecked (on the Preferences->General tab).Make sure UDP is checked for limiting (it's on 2 tabs). If you ever see Disk Overloaded 100%, then slow your transfer speed with the global limiters. It needs to be on a fast local drive (not a mapped network drive), ideally dedicated just for uTorrent. UTorrent does not behave well when its download or download temp folder is shared with other apps (especially the OS pagefile). This configuration was used to help reseed TTD. With the ultimate setup, I had about 900 simultaneous downloads transferring for a combined speed around 35MBytes/sec.
