Slow speeds when minimized to tray, normal when restored.

[Sinxar]

Pretty much as title says.

I am using Vista x64 - 4GB RAM.

I have been looking around here and the closest issue I have found is someone having the exact opposite problem.

The torrent has very few seeds and I limit my DL speed to about 35kB and upload to 10kB (only a 1meg line and have other users).

This is the only torrent i have.

While minimize to the system tray, i mouse-over and it shows it DLing at about 1.5kB and up at 1.0kB.

When I restore the window it suddenly speeds up to about 30kB DL and 10kB upload, and after about a minute it will drop back to the low speeds. Minimizing and restoring again causes it to do the same thing.

The actual speed change has been confirmed by watching my router bandwidth monitor while testing (Tomato v1.25 - WRT54G - No QoS or scripts).

No anti-virus, no firewall other than windows firewall (fresh install) and everything shows as good in utorrent (proper ports forwarded). No other running programs other than Firefox and Pidgin.

I have also noticed this back when i was using the 32bit version of Vista also (abit an older version of utorrent also).

Anyone know what causes this and/or have a solution?

Almost the opposite case?:

Yep, that's the thread I am referring to, but it quickly turns useless.

Not sure what to try to be honest. I'm thinking maybe forcing the application priority higher? that's the only thing that would make sense to me, or possibly disable Cool & Quiet. I have not tried either of these yet because of no seeders online.

I've heard of your problem before, but the solutions in those cases tended to vary depending on what other software they had installed...or how windows was set to run. I believe Laptops tended to do stuff like that to preserve battery life.

I disabled Cool & Quiet in the BIOS and it seems to have solved the issue.
