JSP/Servlet performance tips

Some good tips from Blogging Roller:

  • Don't store too much in each session
  • Don't create sessions at all if you can avoid it
  • Use database connection pooling
  • Avoid string concatenation
  • Minimize thread synchronization
  • Don't use SingleThreadedModel

Couple more:

  • Cache frequently used information
  • Keep the number of database hits to the bare minimum
  • Avoid unnecessary string comparisons

The "Cache" recommendation must be cautioned with "maintain cache coherency". If information is cached from the database, it might miss updates that matter if other processes can change it.

important:
never use class variables in servlets, unless youre 100% sure what youre doing.
