<p>Scott I read the ram x 2= swap in my Linux classes as well and have generally followed that, but with memory soaring as it has lately i am starting to rethink that. A system 48gigs of memory would be 96 in swap..... I wonder if te old format has changed and I haven't heard yet.<br>

I remember from somewhere that upto 2GB use 2.0x RAM above 2GB of RAM go<br>
with 1:1 ratio so 4Gb RAM = 6GB swap. I don't remember why 2x on the<br>
first 2GB and this goes back to when 4GB was a lot on pre-configured<br>
retail boxes. So like Geoffrey I can't see having 18GB of swap for a<br>
16GB machine.<br>
