Starting uTorrent slows ALL network speeds


Recommended Posts

I've been running uTorrent for the past couple of weeks and have grown pretty fond of it. Around three or four days back; however, I suddenly started to experience issues.


Cable Internet Access (Earthlink).

Speed setting 1Mps (originally 2Mps, but I keep switching it)

Disabled uPNP and Dynamic Port

Linksys WRT54GS w/sveasoft firmware (uTorrnet port is forwarded)

ZoneLabs ZASS v.7.0.302 allowing full server/client access to uTorrent.

Everything worked great at first and I was seeing consistent 200+ DL and 100+ UL type of speeds. Then, all of a sudden I wasn't getting faster than around ~20 up and ~20 down. I also noticed browsing the web seemed extremely slow and sluggish.

After some experimenting, here is what I've found:

Rebooting the router does not help. If it was a memory issue, one would suspect that this would be at least a temporary fix...it's not.

Starting uTorrent slows my system wide speed.

For example: Start a 1G download from Fileplant gets around ~500k consistent. Start uTorrent and the speed from Fileplanet drops to 40-80k, even though uTorrent itself is only DL around ~20k. Shutting down uTorrent and the DL from Fileplanet returns to ~500k.

Deleted the %appdata&/uTorrent/settings.dat & settings.dat.old config files and resetup uTorrent. No help.

So, somehow my connection is being saturated even though I'm not moving any/much actual data.

Any suggestions on what might have caused this and what I can do about it.
