FWIW, I've found using an SSD for swap a great way to massively speed things up until the wear leveling really has to kick in. At which point in time everything goes downhill real fast. They seem to be okay when you have a little memory pressure, but when you hit a hard swap storm over a long period of time the drives have a hard time dealing with all of the overwriting of the same data repeatedly. This of course is all anecdotal and may have been caused by a particular version of Crucial/Micron's firmware in their m4 series, but I had ditch my swaps on those drives for fear of losing the whole drive.

Just do some TRIM-ming of empty space on these drives from time to time. Works wonders.

Have you tried enabling the "discard" mount option on the swap partition (or using swapon -d)?
