Stress Testing a PHP server: A wee bit OT

[Darkstar 3D]

If you want to stress test your Apache/PHP server just have a small
little typo like this:

$errCodes=range (910000,9100005 );

in your code instead of

$errCodes=range (910000,910005) ;

Some serious crunching will go on! Off course don't do this on a
production server!

That's not really stress testing a web server... that's just CPU stress,
for any machine. The script will just crunch until the time limit is
reached and die, no biggie (assuming that on your devel machine you keep
a low time limit (like 10 seconds).

If you want to test how well your web server can handle requests loads,
you'd want something like:

http://httpd.apache.org/docs/2.0/misc/perf-tuning.html

Of course, you could also try to get a link posted in a slashdot or digg
story saying something like "help me stress test..." ;)

Justin,

I think you missed the point. The point is how a small typo can cause
big errors. Not really on how to stress a web server. Although, that
typo shot Apache memory utilization up to 1.5GB before coming back down
to Earth. Thats also why the title has "OT" in it.

No links needed, I am versed in stress testing servers. If only my
knowledge of it could somehow be applied to corrective finger movements
so that I don't have typos...now that would be something special.

No, I got it... but I know that some people take everything they read on
usenet literally. ;)

Wouldn't be great if you could insert a chip into your hand for stuff
like that?
