How many proxies do I need w/ GSA? I plan on using it for about a dozen sites. I'm not exactly sure how many threads I'll be using yet, but probably at least 250. I have an old i7 laptop @ 2.3 GHz that I was just going to let GSA run 24/7 on. If anyone could suggest some inexpensive proxy services that work well with GSA it would be appreciated as well.
