I built a test server four years ago on a P100 with 64 Megs of RAM and it was already a pretty slow / old box at that time. Considering that those kind of beasts sell by the pound nowadays, I can't imagine torturing yourself by using a 486 with 8 megs of ram. Even my ancient 486DX50 Toshiba 4700 has 16 Megs of ram in it. IF ons has to develop in such a low end environment you're much better off either writing perl CGI or using PHP, which both use much less memory than JBoss. I don't think I'd try to run JBoss / Postgresql on anything less than 64 or 128 Meg of RAM. Even then you're probably looking at having a fair bit of swapping going on. ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
