Hi,

Though there are some near-miss solutions to this in the FAQs, I couldn't find anything to guide me through this issue. My computer become slow when i start using UT. For example when i tried to play avi file the picture become slow and worse also not sync with sound. Sometimes it just show frame by frame. This problem only happen if i running utorrent.

I had done some troubleshooting with my limited knowledge based on previous problem in this forum but yet i did not solve the problem.

My System Properties :

Windows VISTA Ultimate 32bit

Pentium 4 2.8GHZ

1GB DDR Ram

Maxtor 80Gb (8Mb cache, 7200RPM)

uTorrent 1.7 beta Build 1875

Here some troubleshooting that i'm already done:

1.Change IDE cable with new one.

2.Check IDE ATA/ATAPI controllers' advanced settings properties . (Current Mode : Ultra DMA Mode 6 )

3.Defrag my HD

4.Update BIOS and MB drivers

5.net.max_halfopen == 10

My process explorer :

Process PID CPU Description Company Name

System Idle Process 0 55.73

I have the same issue with the 64-bit Ultimate version of Vista. When i have utorrent running my pc slows to a crawl, anything disk related takes ages.

I've tried to find a solution to this and what i've gathered is that utorrent is polluting the filesystem cache with it's "heavy" io. I'm wondering if it would be possible to improve Vista performance by designing utorrent to make use of Vistas low priority IO function? I can't say that i know much about how utorrent works, this is just a suggestion and a confirmation that the problem exists.
