Subject Increasing Java Startup Performance
Date Thu, 16 Feb 2006 05:05:28 GMT
I went to a this talk this morning

http://www.csail.mit.edu/events/eventcalendar/calendar.php?show=event&id=978

that presented the paper found at

http://www.research.ibm.com/people/m/marnold/arnold-welc-rajan.final.pdf

which implements a very interesting trick to speed up java startup 
performance: save the hotspot information in a repository (at JVM shut 
down) so that the JIT doesn't have to wait when it starts until it knows 
what is a hotspot to start compiling it. the performance improvements 
are not likely to change the perception that java is awefully slow to 
start up on the desktop, but it's a clever idea.

In the meanwhile, Sun's attempt to solve the same problem in JSE6 is this:

No comment.
