Is there a package that would help me monitor the performance of all the
events in my program that I can use to improve my program. Do I have to
preallocate space to ensure StringBuffer does its function more efficiently.
Thanks

Subject: performance tips- was re: Help!
some tips:
0) read Jason Hunter's book.
1) buffer your output-
either to a StringBuffer- or to a
ByteBufferOutputStream
2) set the content-length
3) write all your output in one
go - see above.
4) don't concatenate Strings
use StringBuffer.append
5) cache everything that's
slow- database connections,
-Database metadata,
-user profiles
-small files
6) try to pre-fetch things-
we have a network monitoring servlet which polls constantly in the
background, so there is always
recent data available when a user
request comes in.
7) use a good JIT/JVM
