I'm not looking to start all 50 threads at once. I'm looking to use delay and start 10 threads every 5 minutes untill all 50 threads are started/running.
As already stated, 2000 http client threads. 2000 browser threads would be quite an intensive operation to say the least... You would need a very powerful vps with lots of RAM, but even then I'm not sure BAS would handle it without crashing.
