new protocol sends numbers in hex over the wire. Now the logs are harder to correlate with network events - because numbers in log are decimal (but actually not always, sometimes in hex too!) :
Reducing CPU utilization in the critical paths by changing radix 10 to radix 16, with allows to replace division with shift was more important consideration, than the overhead / bandwidth / memory.
Grep regular expression seems to be reasonably efficient way to find both hex and decimal representations in one pass. For example:
