simulator TCP data rate

[rusefillc]

Windows 11 rusefi_simulator.exe

TS TCP connector shows only 45Hz runtime data rate I was hoping for more?!

next step: run a test with rusEFI code as client instead of TS

[rusefillc]

let's start from a java to java TCP/IP test as baseline

TS talking to TcpServerSandbox is five times faster than TS talking to rusefi_simulator.exe

[rusefillc]

TcpClientSandbox talking to rusefi_simulator.exe

Executed 10000 getSignature in 8250ms Per-signature: 0.825ms Executed 10000 GetProtocol in 1140ms Per-GetProtocol: 0.114ms

TcpClientSandbox talking to TcpServerSandbox getSignature is much faster while GetProtocol is more or less same speed

Executed 10000 getSignature in 1034ms Per-signature: 0.1034ms Executed 10000 GetProtocol in 904ms Per-GetProtocol: 0.0904ms
