I'm not sure why this one project is killing the CPU even at 100 threads, but I guess cause it has most data in it, could 40 URLs and over 400 long spun articles be the reason? (there aren't much engines selected)
It also has tier project with over 800 long spun articles. But even running just the first project with a few others, kills the CPU at 100 threads. Without it, the others can be run at 300 threads as well.
I am posting to a 2M list, but even if I used 200k list, didn't matter.
I am using VPS with 4 CPU 3.60GHz and 4GB RAM.
Should I upgrade VPS to more CPU? Or optimize somehow the data in these projects? Thanks!!
