No. The number of actual processes is not a factor. It's the number of running processes that determines the load. If you have 100 processes, and they're all sleeping the load will be 0.

I mean my bigger machines allow 500 connections while my little Quad-Xeon oy 120.
The number of connections is not a factor. It's the number of actively running processes.
