Profiling

http://en.wikipedia.org/wiki/Java_performance
It seems that much of the startup time is due to IO-bound operations rather than JVM initialization or class loading
(the rt.jar class data file alone is 40 MB and the JVM must seek a lot of data in this huge file).[27]

Haase, Chet (May 2007). «Consumer JRE: Leaner, Meaner Java Technology». Sun Microsystems. Retrieved 27 July 2007. «At the OS level, all of these megabytes have to be read from disk, which is a very slow operation. Actually, it’s the seek time of the disk that’s the killer; reading large files sequentially is relatively fast, but seeking the bits that we actually need is not. So even though we only need a small fraction of the data in these large files for any particular application, the fact that we’re seeking all over within the files means that there is plenty of disk activity. »
