Hi Abdullah,

Can you share your ModSecurity startup information? It should be in your error_log, something like this:

[...] ModSecurity for Apache/2.7.7 (http://www.modsecurity.org/) configured.
[...] ModSecurity: APR compiled version="1.4.8"; loaded version="1.4.8"
[...] ModSecurity: PCRE compiled version="8.31 "; loaded version="8.31 2012-07-06"
[...] ModSecurity: LUA compiled version="Lua 5.1"
[...] ModSecurity: LIBXML compiled version="2.9.1"

Did you tried to compile it without pcre-jit support? How is your cpu and memory load while performing this request? every request is slow? or just specific ones?

Hello,
I have IBM IHS (32 bit) installation on Linux server.

I downloaded mod_security, compiled it successfully and start using the
mod_security2.so file in my IHS server 

I loaded the library file ( so file) inside httpd.conf file. Once I load
it, although I don't define any rule , opening apply application via this
IHS will be extremely slow  and it is taking more that 500 seconds to open
one jsp file.

while, If I comment the loading line /restart IHS server and test my jsp
it is opening  within milliseconds.

file download from site :modsecurity-apache_2.7.7.tar.gz

1- alias gcc='gcc -32'
    export CFLAGS=-m32
