I am writing a java program, and I have a test to see what is the performance of my program.
While it has difference result when I run it directly in eclipse and export to a jar.
Running directly in eclipse is 2 times faster.
Can anyone tell me about the difference between:
1. Run from eclipse
2. export to jar
Probably the difference you see is the extra time you need to load new classes in execution time from the jar, as it is compressed it needs to do extra job to find the file and load it. while Eclipse uses unpackaged files so it is faster.
