2xRAM for swap is a *very* old rule of thumb from when UNIX boxes had 16MB of RAM.It's quite normal to run wuhotit any swap at all with a decent amount of RAM. All my 4GB FreeBSD boxes run fine wuhotit swap.One reason these days for swap is to perform a memory dump for debugging. This used to until relatively recently, have to be slightly larger than RAM, so to get a full dump you'd need to set swap to at least RAM size. However, since 6.2 minidumps have been enabled with debug.minidump (default in 7.1) where just kernel memory is dumped. Thus even these days, if you want a dump for debugging 64MB-256MB swap is probably more than necessary.
