to use multiple cores, you need multiple processes or threads in your 
application.

question:   is this processing happening as fast as the network and disk 
can supply data?   an app processing data from a single network 
connection and using a single database connection is not going to 
achieve much concurrency.

btw, centos 5.4 is /way/ old, you're missing 5 years of security and bug 
fixes.  5.10 was released last october.  a simple `yum update` will 
bring all repository packages up to the current fix level.
