The best way is to use some kind of profiling tool, this will tell you where most time is being wasted and help focus your efforts. I have not used any profiling tools with EJB's so I cannot recommend any.
If you execute any SQL, tune that as best you can before touching java code. Look to decrease first the amount of SQL calls you do, perhaps by refactoring your code, and only after that look to improve the speed of individual SQL calls. This can be done without a profiler by capturing a sample piece of SQL in a debugger or a log file, (or even building the equivilant SQL by hand.). If you cannot get hold of a good profiler then do your own timing using System.currentTimeMillis() before and after each thing you want to time and subtract the two - dump the result out to some kind of log. Start quite high in the call stack and work your way down to the offending code. Fix it. Look for: lots of String manipulation - use StringBuffer, slow hashcode genaration of objects that are keys in hashmaps and hash sets. > -----Original Message----- > From: Ram [SMTP:[EMAIL PROTECTED] > Sent: 18 June 2003 01:12 > To: [EMAIL PROTECTED] > Subject: Re: Performance Tuning > > I know making them execute faster is called performance tuning...
