Today's rant:
The C standard libraries after about 1995 weren't focusing on
performance. The non-"n" string library functions are pretty well
optimised for NULL strings.
Don't model stuff on the C standard libraries if you want anything
performance critical. And don't use C standard library calls if you
want anything to run fast.
Case in point: argh don't use *scanf and *printf in the critical path..
You haven't done that, but thats dotted all throughout the Squid codebase
and its really freaking irritating. Half the speedups in 2.6/2.7 were
me going through and slowly replacing all the stdio calls in -socket-
code.
