I have installed Eclipse 3.4 / MyEclipse 7.0 M2 on an intel iMac with a C2D (dual core), running OS X 10.5.5.
After checking out a rather large project, I noticed validation of my JSP files took a rather long time. Upon closer inspection using the progres view in Eclipse and top from the OS, it seemed that ME is using only 1 core on my setup.
Each JSP file is validated right after the other. Since the process is very much CPU bound and individual JSP files have no dependency on eachother, this seems to be a prime candidate to utilize multiple cores. A major theme for Eclipse 3.4 was the utilization of many cores, which have become very common in the last years, especially on developers machines.
Can you let MyEclipse validate in parallel? Or this already possible and did it somehow failed on my Mac?
Henk,
This is an enhancement on our TODO list for a future release, no planed ETA for it yet but the ground work was laid in 7.0 to eventually support it. May not show up until 8.0 or so though.Please hurry up with this 😉 I’m on a quad-core now and have to wait a long time for validation to finish, yet 75% of my raw CPU power is left unused. I plan to move to an oct core workstation in the near future, but MyEclipse will then leave 87.5% unused. It would be really cool if you could take advantage of this extra horsepower.

Im sure this would be really cool feature. I’ll add another vote in favor of this feature from your side.
Any news on whether this is in 7.5 or not? Got a triple-core box now that’s waiting to be used fully! 🙂
Karsten,
We don’t explicitly take advantage of multiple cores — but the VM should utilize multiple cores for multi-threaded applications, and fortunately all our builders/validators/etc. are all multithreaded — so during a full build that should take advantage of it.
