utorrent heavy ram usage


icsterm

Recommended Posts

Utorrent is using 500MB+ of memory in task manager, abnormal in my opinion.

I use the following setup:

-external 7200k rpm hdd via usb 2.0.

-both windows write/read cache are disabled in settings.

-write cache disabled ( when enabled, it stucks with disk overloaded at about 8-9MB/s).

-read cache enabled.

My download speed is 11MB/s constant.

But ram usage of utorrent.exe process is increasing (sometimes up to 1GB).

Why?

Because i don't use any cache (both windows/utorrent).

Is it because i use Windows Vista x64?

Please advise.

So writing to hdd is done in realtime and ram usage is just a side effect? (this particular ram usage is different from the standard utorrent cache that i disabled? ).

At the time i uploaded the pic, RAM usage has reached 2GB!! ( i have 4gb total ram memory).

Torrent file has 60GB filesize.

Later edit: The utorrent.exe ram usage is using a fixed amount of ram near 2GB, because of windows vista limitations. Speed has decreased about 2Mb/s. I think i should limit the speed to this value in the future.

Any tips to get maximum speed without involving this huge ram leak?

I will unload Avira services, and try to download again and see if any changes occur.

How can i manually unload the dll ? (without uninstall of Avira).

Edit: i got results by increasing half_open limit, seems like an utorrent bug (i had my limit set at 5, not default like it suppose to be at 8)

Now ram usage is ~200mb constant.
