Around 2002 I had bought a machine with a duron cpu, which required a different kind of memory.  I still had lots of memory for my old machine, something like 768MB cobbled together out of 64-256MB DIMMs.<p>So I created a ramdisk on the old machine, exposed it as a nbd (network block device), mounted it on over the network (one hop over a 100 Mbit switch, didn&#x27;t have Gbit kit) on the new machine and created a swapfile on it.  I couldn&#x27;t believe how well it worked.  I never actually had any flakiness issues and I used it like that for probably a year.
