I created a campaign with Social Bookmark, Social Network, Article and Micro Blog - all in one project. I imported a list of ~ 550k url - made of smaller lists with footprints from platforms that I mentioned above. Search Engines are disabled. HTML timeout 120. I use 10 private, working proxies. For captchas I use CB, 1 retry. No pr, obl filters. Also use urls from global site lists - submitted and verified as well. I created 13 fresh hotmails specially for this campaign with spam filter disabled. All filters that could slow down my projects are disabled. I use spinned content only. 1-2 random urls for random words and 1-2 random images are enabled. The problem is - ser runs on 100 threads(as in settings) for a few minutes and then it slows down to just a few 3-10 and again, number of threads increase to ~100 and slows down. Maybe it's totally normal and I shouldn't even ask this question. However I need to get a lot of links in tier 2,3 and it's hard to achieve when the program suddenly drops down to even 1 thread - and it keeps up on 1 thread for a few good minutes.
