Yep, even if you machine suddenly gets twice as much memory it doesn't mean your processors double their cache sizes, right? Seriously, we at JetBrains had tried that VM. It have proven to be slower, more sluggish especially on startup (server VM classloading penalties?), longer GC pauses (server optimized garbage collector algorithms?), have seen a few core dumps and some visual glitches. So I wonder why this question comes up again and again?
Lucky me, I have been using it on my MacPro for all of the 8 EAP for a fairly large maven based project - no complaints, fast enough for me, no bad bugs - so far
The MaxPermSize was necessary because I have a large project (36 modules). I found that IDEA would lock up. I checked out Console and it showed the errors about running out of permgen space.
I've got 8GB in my machine (2 x 3 GHz Dual-Core Intel Xeon) and frequently see my VM size go over 90GB but the machine ends up with 2GB free memory. So no swapping or page outs occur.

At least for Flex development I would not recommend it, see http://www.jetbrains.net/devnet/message/5228396#5228396.

Menory is cheap. I gave Idea 4G and we make a very happy couple ;-)
Like cheap corner store roses, it does the trick. :-)

Just an update -- for the past several days I been running with Java 6. Performance is fine. I boosted the memory settings as so:
<key>VMOptions</key>
<string>-Xms256m -Xmx1024m -XX:MaxPermSize=512m -Xbootclasspath/a:../lib/boot.jar -ea</string>
The MaxPermSize was necessary because I have a large project (36 modules). I found that IDEA would lock up. I checked out Console and it showed the errors about running out of permgen space.

I am happy with the machine's performance.
