Nearly all optimizations made without measuring real code in operation are premature.

"We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil." (Knuth, Donald. Structured Programming with go to Statements, ACM Journal Computing Surveys, Vol 6, No. 4, Dec. 1974. p.268.)

Understood,these are ideas once you find the bottelnecks after benchmarking the performance measures.

Most of the measures I have found usefull were from the log statements(log4j) with timestamp.

And your ideas are decent places to start once you've profiled the hot spots. Netbeans has a decent profiler that I've used. I'm sure there are lots of alternatives.

You kit on the big on: Don't clank the database.

Its worth 1000 lines of code to avoid a clank in a hot spot.
