Interesting results for getservbyname() performance (and possible changes for /etc/services)

[Callum Lerwick]

Err, how often are service lookups done? How performance critical is
this, really? Seems to me an application doing a large number of lookups
is best off just slurping in /etc/services itself (Or just keep its own
service list) and building its own hash table in RAM or whatnot. (Which
IIRC is what stuff like nmap and ethereal do...)

Benchmark a real application first, then optimize. ;P
