utorrent use 25+ % cpu

[Noein]

Hello after update to version 3.1.3

after I start any torrent cpu usage hits 15% ( 25% when I got Overclocked cpu ) .

Before with it was always 0% so it is very strange .

My setting.dat have 15 KB

and I didnt changed anything with dics cache and so on . I tried to return to old version but again it use 25+% CPU . Any ideas?

The same for me. CPU usage is 25-47% at downloading time. Totally unusable.

What is your firewall or security software?

[smklimenko]

DOn't have software firewall but have router. I'm using Avira Free Antivirus 12.0.0.898.

I found one correlation: download speed. Usually it's about 2.3Mb/sec (WiFi) and it takes 30% CPU. but if limit speed, for example, 700Kb/s, it's 10%. If download speed 400Kb/s - 1-2%.

I tried disable antivirus but no success.

Try uninstalling Avira completely. Disabling generally doesn't work.

Also, what CPU does your machine have? Are you leaving the uTorrent window open while downloading, or do you close it (and let it sit in the tray)?

I got microsoft security essenctials + routher

and it start taking cpu when torrent is added ( its not even dl/uploading it Oo)

cpu intel core i7 950 when its on stock clock 13% usage even if utorrent is minimalized

if 950 is at @4,0 utorrent use 30-40% cpu
