The most important thing before doing any work on optimizing, is indicating what needs to be optimized. Thousends of tips to optimize can be posted here, so it's better to find what your performance problem is, and ask a more specific question for help to optimize what you need. You can optimize 3 parts of a web application:

Serverside performance: Indicate the largest bottleneck (a profiler is an easy option to do that). Optimize the bottleneck. Optimizing smaller problems, or optimizing without measuring the amount of time can be a waste of time when the large one is still there.

Client side performance: Take the advise from tools like yslow, or google page speed.

Bandwidth: Send the smallest amount of data to the user as possible in the least amount of requests as possible.
