Yes, one telegram is one packet.
UseNagle is deactivated on Client and Server only one time (in object inspector property of component).
I only checked before I call "write", if UseNagle is really deactivated. Yes it is.
I test it with Delphi 12 in Host machine (=server) and virtual machine with Delphi 12 (=client).
I try to reduce my source code to a demo project but actual it isn't so easy because it is full implemented in our company software. I will try it...
Thank you for replaying, and i don't care about the data, just a code like other and older samples/demos in this thread, but something shows this behaviour of delay or higher CPU usage..etc.
Preferably without inline var as i don't have them.
