The guideline I use is...
Prioritize Use-Cases based on R/W, Frequency
Try to optimize the the most frequent Use-Cases
Test/Profile you app; often this leads to the following,
Optimize database queries since I often find this to be the bottleneck.
- Cache objects if you can in memory to avoid DB Queries
- Add proper indexes to queries
- Do more work within the database if you can
- Batch TXNs
Use less Java objects,right collection types, algorithms.
I wonder how much of a performance boost tweaking Tomcat will achieve.
I rather not spend time trying to boost Tomcat, unless I absolutely have
to.

one more note. Persistence is the only effective tool
for high performance! No amount of money or talent can
beat persistence when it comes to making sure your
website works reliably and responds within a set time.
