    Default How to speed up the performance of the java application

    Hi All,

    I have installed my java application in the physical device (PDA- MC75), THe performance of the application is very slow.

    How can i improve the performance by application wise rather than the hardware solutionas like clearing temporary files, Device memory, etc...

    Any thing i need to change in the java code level ?

    Thanks in advance .

    change in the java code level
    There are profiler programs that will show you where you code spends time when executing.
    You could run some of them to see if there is any place you could optimize the code, like an overuse of String concatentation with large Strings.

    Please do not post multiple copies of the same question in different posts. I wasted time responding to your other post with pretty much exactly what Norm already said.

    But yeah, this really depends on your code. It could be that you're doing something silly. Use a profiler to figure out where your time is being spent, and if you still need help, use that to create an SSCCE that demonstrates the inefficient code.
