No, that doesn't matter. I think you should be looking for how quickly it can get you a working environment for your favorite language not how long it takes to boot up once per reboot. If you want features the bits have to live somewhere. Look at it like a trade off, if you're just going to look at it, by all means, take a memory dump. But I find that a little bit hard to work with.

For me, as long as it's better than alternatives it's good enough. Especially if it's not running JS.
