Nothing special: super-smack smacks/select-key.smack 4 1000 Or so; change the number of clients and iterations to taste; you'll note performance does improve slightly with more clients up to the number of CPU's and then drops slowly as you add more, with system load apparantly not increasing a whole lot; I'm not even sure it got past 50% most of the time, despite there being plenty of active clients. It'd be interesting to see this comparison with PgSQL; super-smack supports it, and as a preforking database server it might do better on FreeBSD. -- Thomas 'Freaky' Hurst - freaky@aagh.net - http://www.aagh.net/
