ArchaeologicalMonstrosity Posted December 10, 2012 Report Share Posted December 10, 2012 I'm using a bitcoin miner, which maxes out my processor and graphics card both at the same time. While doing this, uTorrent will not write files to the disk, or will write very slowly.I have uTorrent set to high priority and the miner set to lowest. It has the processor time, but is choosing not to use it.To reproduce:Download something in uT while maxing processor, maybe folding@home or bitcoinWatch disk statistics in Speed tabSee cache fill up and hdd not being usedStop foldingSee cache empty quickly, and immediately.

ciaobaby Posted December 11, 2012 Report Share Posted December 11, 2012 While doing this, uTorrent will not write files to the disk, or will write very slowly.And you are surprised at this behaviour ..given this information ... which maxes out my processor and graphics card both at the same time.because???I have uTorrent set to high priority and the miner set to lowest.Permanently or just for the current session. It has the processor time, but is choosing not to use itNope! Windows is 'choosing' NOT to give uTorrent more CPU time.The applications have no control at all over the processor time that Windows gives to each running instance.

ciaobaby Posted December 11, 2012 Report Share Posted December 11, 2012 By the way, when you set priorities did you also set the CPU affinity for each process, assuning you have a multi-core CPU of course. Link to comment Share on other sites More sharing options...
iD4NG3R Posted December 11, 2012 Report Share Posted December 11, 2012 I'm using a bitcoin miner, which maxes out my processor and graphics card both at the same time.Mining on your CPU is useless, turn it off. While doing this, uTorrent will not write files to the disk, or will write very slowly.Had this problem to on my older rig. I have no clue if this has been done intentionally or is a bug, but I've had it years back.I have uTorrent set to high priority and the miner set to lowest. It has the processor time, but is choosing not to use it.Even when setting a task to "High priority" in the task manager, this does not mean it will get said CPU time. If another application simply keeps hogging your CPU uTorrent wont be let through. Try loading your CPU with Prime95, and give some random application a high(er) priority. Nothing will happen to said application.Even if this is a bug: Please stop folding/mining on your CPU. Its an utter waste :< . Link to comment Share on other sites More sharing options...
Kitsoran Posted December 12, 2012 Report Share Posted December 12, 2012 CPU mining is nearly worthless. As to why µTorrent can't write to disk, it's probably because the devs set the IO thread priority to low. Link to comment Share on other sites More sharing options...
Latency Posted December 13, 2012 Report Share Posted December 13, 2012 This bug seems to be closely related to the problems experienced here as well:Completed torrents are slow to move due to very low I/O priorityuTorrent 3.2.2 - Disk overloaded 100 %Just ignore what ciaobaby is saying, since they don't seem to have the foggiest idea of how software works.There is indeed a bug with the disk IO here, as the IO thread seems to be getting starved even when the Process Priority is increased.
