I think the public proxy scraper should almost be removed from GSA...it leads people to have a poor experience. The number of threads related to this issue is high and it's almost always due to not using private proxies!
I'm experiencing problems with threads slowing down to a crawl lately. I've tried it all, without proxies, with private proxies, with public proxies, proxies for search only, for posting only... It works fast at first, but after some time, it feels like it's using only one thread at a time. I'm using Ozz's search engine selection.
It's weird, because it was posting really fast some time ago, in previous versions.

Might check your proxies.
