Just create a file say
test2.html in htdocs/testsub/ directory which contains :
----------------------------------
hello world.
<repeat 500 times above line.>
----------------------------------
Alias /testsub/ "/usr/local/apache2/htdocs/testsub/"
LoadModule substitute_module modules/mod_substitute.so
<Directory "/usr/local/apache2/htdocs/testsub">
Options FollowSymLinks
AllowOverride None
AddOutputFilter SUBSTITUTE html
Substitute s/hello/hi/n
</Directory>
Now run the stress using ab :
ab -c 400 -n 400000 http://hostname/testsub/test2.html
Notice the size of httpd process. It will keep increasing to several GBs.
I tested with worker mpm (httpd-2.2.6) 64 bit on Solaris x86.
<IfModule worker.c>
ListenBackLog 50000
StartServers 2
ThreadLimit 500
ThreadsPerChild 500
MinSpareThreads 100
MaxSpareThreads 1000
ThreadsPerChild 500
MaxClients 1000
MaxRequestsPerChild 0
</IfModule>
