Message6108

We have run into this same issue. Our program starts in 15 seconds with the normal standalone jar and with class files included this drops to 9 seconds.

Our system (Robot Framework) is restarted repeatedly in some environments, so this is a serious speed issue for us.

Here example times with just some simple imports (as noted, our program shows even bigger time differences):

time java -jar compiled.jar  -c 'import unicodedata, os, time, unittest, datetime, subprocess, zipfile, httplib'

real	0m6.710s
user	0m10.816s
sys	0m0.462s

time java -jar not_compiled.jar  -c 'import unicodedata, os, time, unittest, datetime, subprocess, zipfile, httplib'

real	0m8.858s
user	0m13.664s
sys	0m0.412s
