Very high RAM over 1,9 GB 100/100 Mbit line


Recommended Posts

So i have been searching a fix for a long time, i have been checking these forums and seen people

with similar problems but no good solution.

The problem is that when i download a large file or multiple smaller ones (3 torrents around 1 GB).

As the speed goes up so does the RAM when it goes around 1,9 GB the uTorrent process hangs

and a force kill is issued by hand.

Info about my setup and what i have tried:

I have a 100/100 Mbit line and i'm downloading from private trackers so i hit max speed all the time.

I have had this problem on a XP SP3 box with 4 GB RAM (Not all usable because of X86 processor)

Client used now is 3.2 Beta (Build 27215) [32-bit] I have tried with a stable version

So i though that a fresh install of a Windows 7 Pro X86 would solve the problem but it did not.

I have played around with the settings but when i find a setting that stops the RAM growth the speed is affected to a total failure.

I am having uTorrent downloading to a external USB now but i have had it download directly to the local SATA drive with no change.

The logger show no errors while downloading.

Some bandwidth settings:

Global maximum of connections : 2500 (Tried 100)

Maximum of connected peers per torrent: 2500 (Tried 100)

Number of upload slots per torrent: 1000 (Tried 100)

I have tried to put these settings really low but as i hit max speed the RAM goes up like crazy.

Disk cache settings right now:

Override automatic cache size and specify the size manually (MB) : 256 (I have tried to uncheck it with now difference)

Reduce memory usage when the cache is not needed: checked (Tried with unchecked)

Enable caching of disk writes: Checked

Write out finished pieces immediately: Checked

Enable caching of disk reads: Checked

Disable Windows caching of disk writes: Checked

Disable Windows caching of disk reads: Checked

I have tested different settings with Disk Cache but when the RAM stops to grow so does my speed.


Everything is default here.
