As per my question up at http://apple.stackexchange.com/questions/65640/why-ever-does-parallels-8-recommend-max-4-gb-ram-for-a-vm, I'm a VMware Fusion user and am trying out Parallels since VMware has some quirks that are annoying on Mountain Lion on a retina MacBook Pro (16 GB RAM).
I'm wondering about the baffling Parallels recommendation (when configuring a VM) that there is a maximum cap of 4 GB of RAM for a VM with Parallels (indeed, it recommends 1.5 GB for Windows 8). (See forum thread at http://forum.parallels.com/showthread.php?t=114040). Granting anything more would, in fact, slow down both the host and client, but I have no problem assigning 8 GB of RAM to a VM in Fusion; before really committing to Parallels, I'd like to know the rationale behind such a recommendation (and no, the Parallels forums don't shine satisfactory light on the subject, at least from what I've been able to dig up). If you're running in an x64 environment for both host and client then there shouldn't be any acceptable reason for needing to cap the RAM. Apparently, Parallels support states 'because Windows is working in a virtual environment, that it only needs max 1-3 GB.' My development machine and environment is not a toy, so such an answer seems borderline patronizing and makes me think they're simply covering up for a significant Parallels limitation.

I've got a last-generation black MacBook with a 2.4 GHz Core Duo processor and 2GB RAM. Parallels 4 is running all right, but holds the rest of the machine hostage in terms of performance, even though there's still available memory and processing power. What can I do to get more balanced performance for when I need to switch between Windows and OS X?

Just FYI -- In every case I have seen, you will see a performance gain in switching to Parallels 5..
But to answer your question, what applications are you running? Download parallels for mac os x 10.6.8. That is a fairly important issue here..

Refund policy for parallels mac. But, with the 2Gb of RAM, you will want to probably allocation between 512 and 768 Mb of Ram. Defintely no more than 768. Please start at 512 Mb, and slowly work your way up to a max of 768.
Why? You are basically reserving up to 1 Gb for the Mac OS.. Within the 1 Gb 'free', Parallels will consume some memory, leaving up to 768 MB of Ram for the Virtual Machine.

Please consider at least upgrading to 3 or 4 gb of ram. I have seen nice improvements in virtual machine behavior when more memory is available.
