Eclipse at the speed of light

If you’re a little bit like me, you’ve been fooling around with VM Startup parameters for quite some time now in order to get your eclipse running as fast as possible. Maybe you’ve even changed VMs to jrockit and so on to make the best of your programming experience.
At least after switching to quad-core processing power, you’ll notice that your suspicion was right all the time: I/O is the main bottleneck with large depenndent projects.
Well, this wisdom gained, i switched from raid5 to raid0 and added an extra 256mb to my raid controller. This has greatly improved the “rebuild-workspace” experience.
But after this weekend the conclusion is obvious: all this is futile!
If you’re really interested in getting eclipse run fast (at least on a 32bit system, where main mem in limited) go get one of these:
Gigabyte-IRAM , and make sure your workspaces together with eclipse and the JDK fit in 4gb. (otherwise cleanup your plugins and seperate those workspaces really needed to be fast from those of minor interest)
I have this configuration running and been beating it hard for a day now:
it is just awsome!
if you’re as afraid as i am to loose any data (even though frequent commits are a good CI technique anyway), you can use rsync to backup changes to harder disks now and then.
