TCP_NODELAY #2

Closed wolfc01 closed 9 years ago

wolfc01 commented 9 years ago

Hello Benjamin,

Just some backing info on the sockets:

please note that TCP_NODELAY disables the nagle algorith in the socket: that is, if the sender sends a small package, TCP IP will send this package immediately to the receiver. Normally nagle algorithm is ON, meaning that the TCP/IP stack (may) optimize by aggregating packets together in order to optimize throughput, but ruins timely passing of messages.

We use this option to have quick passing of small messages.

I think with SECS/GEM this is not necessary to do, or am I wrong?

Best regards Carl.

Hi Carl,

you might be right. I don't think the hsms protocol is that time critical.

Thank you again, Benjamin
