some benchmarks
hi.
i've started doing some benchmarks. cgi+c, php, dtcl and aolserver
included for now.
take a look at http://213.25.140.2/z/
apaches=apache static (everything static compiled).
i used:
apache=apache 1.3.14 (from debian/potato)
apaches=apache 1.3.20
aolserver 3.4
mod_dtcl 0.11.0 (dynamic for apache, static for apaches)
php 4.0.3 (from debian/potato)
tests were performed on a p3 733mhz machine with 192mb ram on 2.2.19
kernel.
what bothers me is that tcl is twice as slow when doing sin() on a
loop. any ideas on how to speed that up? [except using loop from tclX]

What kind of test have you performed? There's no description

twice as slow respect to what? And, also, it's just sin() you want
to speed up or, more in general, math functions?
---------------
Note:
You could try to approx. sin() with something like
1/2 x + 1/6 x^3 + .... , but I don't know it it's faster (and if you can
use it).
(see a math book for the Mc Laurin approx. of a function. It's been
a long time since I really used those things).
