That's hard to say. I've done SW raid 1 too, and my guess is that the
raid won't be much of an impact. Writing is a bit slower, reading a bit
faster. However, that box has 1G of ram, and I don't know how much raid
actually uses.

If you're concerned about swap performance, you could not mirror the
swap partition, but that kind of defeats the purpose, and I wouldn't
expect that there'd be a noticable performance gain.

Of course, the more ram the better!
