Optimize webserver performance

[abhishek jain]

Hi friends,
I  have a few different applications running on a small VPS, tomcat 5.5.x,
struts 1.2 , mysql.
I need to know , what can i do to optimize the server files, like can i
place the mysql-..jar file in the tomcat commons lib folder. ie should i
place all the common files i have in all my applications in the commons
folder of tomcat, so that the same file is not loaded individually for each
project,
Pl advice.
