Tell me why I run a project with 50 threads, but there are always 6-7 active browser windows. It is clear that there are 50 threads, but much fewer windows are launched at a time, although this was not the case before.
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.
