benchmark: calibrate config dgram multi-buffer
Replaced the
num
config withn
to be compatible with then
CLI argument.Looking at the outputs:
Chunks 1 and 2 have very similar results, as do 4 and 8. I removed 2 and 4, keeping only
[1, 8]
.I think
[64, 512, 1024]
covers a sufficient range, making256
unnecessary.If you don’t agree with the changes in the configs, let me know, and we can revert them and just proceed with the
num
→n
