how to make tomcat faster

[Anoop Kumar V]

hi,

i have been developing using Tomcat 4.0.1.. and i hv had no problems about
that.

Now i have moved all my applications on to the production server, where
hopefully i
wdnt be making any more changes. But i want to make Tomcat respond faster to
requests.
Obviously the production environment shd be different from the development
one..so 
can someone detail me on what changes i can make to make Tomcat quicker to
respond.

Thanx in adv,
