I've been developing RoR apps for about a month in my Windows Laptop, however everytime that I run the tests it takes forever to finish (10+ minutes).
On a MacBook Pro with similar hardware it runs in a fraction of the time (2 minutes). Can you guys give me any tips for speeding the whole thing up? or should I consider switching my RoR environment to a Linux/Mac box?
I do most of my ruby development in an Ubuntu VM, just because it is easier to get everything together under linux (I imagine the same applies to OSX). RVM makes my life so much easier.
If your hardware can support it and you don't mind working in a VM, may I suggest you give it a try? VM development has its advantages (namely, taking daily snapshots so you can roll back environment changes) and disadvantages (you lose a bit of speed, but not much these days) but I think it is worth it overall.
