For some time now on 64-bit platforms the recommendation has been "at
least 20G of swap" no matter how much RAM you have. If you have ever
studied the SAP memory management system you can see why. The general
argument goes that 20G of swap is considerably cheaper than having
your multi-million pound business down for half a day whilst an admin
(or expensive external consultant) debugs a memory issue.
