TCP Benchmarks

Connections Test
We also test only the raw KingNetwork library by spawing 1 server and 1000 clients, each client sending 100 bytes 14 times per second and the server echoing the same message back to each client. Test Computer: Acer F 15 with a 2,9 GHz Intel Core i7 7gen processor and 32 GB ram DDR4.
Test Results:

Clients	CPU Usage	Ram Usage	Bandwidth Client+Server	Result
64	0.5%	9 MB	0.3 MB/s	Passed
128	1%	10 MB	0.7 MB/s	Passed
500	18%	18 MB	2~3 MB/s	Passed
1000	32%	26 MB	5~6 MB/s	Passed
