cool.

Under Linux, I have a much more powerful tool: valgrind massif - which
can count how may time and memory a program takes to run ( as Josh
told me be, memory space is always a tradeoff ). Massif even can tell
me which functions take more time or memory.

For both Linux and Solaris, my load test is as simple as: Start with a
large number of c ( like 1000 ) run ab -n n -c c URL, decrease c until
the web server load usable. I check it by open another browser and try
to access another URL of the server.

FYI, it seems that to get a boost, we have to use optimized version of
Apache (+PHP):
  	CSKamp_1.2_sparc.pkg.bz2
