I don't have fusion, but i run parallels. not exactly the same, but probably similar memory requirements. it was a dog with 4gb, sl, itunes, iphoto, pshop, mail, and some firefox running alongside. I upgraded to 8gb, and it's many many times faster, smoother, almost no waiting for beachballs, etc......Thus, I would love to get some feedback from people who have been running Fusion and Windows under the kind of circumstances I would be facing if I got an upgraded MBA. This thread seemed to me to be a good one in which to ask my question.

memory pageouts have gone from the hundreds of thousands to a thousand or so.
hope this helps.
Thanks to you both for your feedback.If you run Win7 in virtualisation 4 would suffice but more than 4 would be ideal.
I had the same problem. Turned off swapping (disable dynamic_pager) and what do you know, my MBP got a lot more responsive! Didn't experience any problems without swap, even using VMware Fusion. No more beach balls waiting for pageins!I regret getting only 4GB with my new mbp; the computer's paging-out about 30% of the time by the end of the day :/
Just adding my £0.02
Just a thought - would eight gigs of RAM have an effect on the lifespan of an SSD, seeing as how that would reduce (if not outright eliminate) pageouts?
I am inclined to agree with the proposition that one is likely to upgrade to a larger SSD before the original fails. We are at a very early day of SSD development so it seems inevitable that SSDs are going to become both cheaper and faster rather quickly.I would guess it to be negligible. You'll probably upgrade to a bigger/cheaper/faster SSD long before its useful life is over.
I don't have an SSD drive, so take what follows for what it's worth. The conventional wisdom seems to be that even when an SSD drive loses some of its original speed, it's still dramatically faster than any conventional drive.I'm not too concerned about failure in the sense that you generally associate with hard drives; I was thinking more about staving off the gradual performance degradation (although after reading countless threads about it here, I still have no idea what the timeframe is on that). I'm getting the impression that it's less of an issue than some make it out to be, though.
When Fusion is not loaded into memory it doesn't use any RAM. Once Fusion is in memory with Windows running in a virtual machine, though, it is using RAM, whether or not you are actually doing anything in Windows at the moment.This maybe a foolish question, but is Vmware or parallels continously using RAM-memory or only when I'm using it? I have to use W7 every now and then, now I'm working through Bootcamp, but I would like to work parallel with OS.
