Intellij IDEA X: any multicore settings to be tweaked?

I've got a nice Mac Pro 开发者_StackOverflow社区with 4 cores + Hyperthreading. Are there any Intellij settings to be tweaked to take advantage of this? Either through the GUI, or by editing the Info.plist file?

I'd be especially interested in making GWT compilation/execution faster. (I already have localWorkers 4 set).

Thanks

I don't know if this will help, but it sure looks interesting:
