In the old days (and they weren't "the good 'ole days") you had too much swap so that a production long-running server wouldn't crash if something started chewing ram. It'd still run, ever slower, giving you time to find the offending process and kill it. In the last 5 years though most unix systems will kill off memory hogs themselves rathering than dying themselves. > But if I have 1G of memory it certainly seems like 2G of swap is too much. > Couldn't I just get by with 1G swap, or should I allocate 2G to swap? As others have said, a gig of swap is a good thing. For a laptop, you could use a lot less, depending on your use patterns, but might need more for that hardware suspend. You should already know if you're a heavy memory user, and it sounds like you aren't, so go with a gig and don't be concerned. If you do find you occasionally you need more ram, you can easily add some more swap. dd if=/dev/zero of=/SWAPFILE bs=1024k count=1024 # (a gig) mkswap /SWAPFILE swapon /SWAPFILE -- Ted Deppner http://www.deppner.us/ _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
