Since the last few versions of GSA, no matter what amount of threads I set it on.. 100, 150, 200, etc, it moves very slow. It 'appears' to be using the threads (shows it's using all 150 threads for example) - but they just stall for a long time during the submission. Like it's moving on only 1-10 threads.
I monitor my bandwidth on router and seems it bounces up and down pretty drastically, where it used to maintain a more constant speed. Internet connection is 100mbps down / 20 up. PC is Core 2 duo 2.4ghz, 4gb ram.. CPU usage always small %. Captcha setup is CB as main source, CaptchaSniper is backup.

Global list only (no search engines), PR2+, and extension filter (only blocking .ru and .cn).

I'm wondering if it's a problem with just this PC - but I have been using it no problem for several months.
