Well, by default I am only checking the CRC32 checksum and have a test and a
branch for a global variable. So the question is what is the impact of the
extra load of the global variable?

Do you have a benchmark in mind? Something as simple as one connection and
sending messages between two machines? Or should I guard this whole config
with a kernel config right away?

I wish I could, the machine is on the edge of the network and not in my control.
