Of course this is cockamany, urban myth, etc and typically you increase RAM and need even less swap than before for eg (my desktop) Mem: 4036296k total, 4014656k used, 21640k free, 96400k buffers Swap: 1004020k total, 32k used EXCEPT for 1 tragic circumstance: Never *suspend* unless you have as much SWAP as RAM. Suspend writes all RAM starting at the beginning of swap and over everything along the way. (and I activated suspend by dropping an earring on the keyboard :-) So if your use scenario has never used all your swap, add RAM and forget about adding swap otherwise do the math James -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
