It's only too much until you actually need to use it ;-) For example, if you have 2GB of memory then you need a 2GB swap file in order to take a kernel crash dump, if you ever run into a kernel bug. You only have ~1GB of RAM in that machine at the moment, so you might be tempted to conclude that you have 1GB too much swap, but what if you decide to add another 1GB of RAM in 6 months time? You'd have to reinstall that disk to make room. Kris P.S.
