Especially if you do a large compile or something of that nature. Going from 80 MB to 256 MB isn't that big of a step, esp. if it's a desktop system. Going from 256 MB to say 1.5 GB you should see your percentages drop somewhat. That is, for a desktop system. Remember that the memory usage statistics also contain shared memory and memory that is cached application data, which may be cleared and reused if a new application needs it. Also, in a server system, if you had 1 GB of memory and only showed 500 MB used, you'd have 500 MB of wasted memory to pull out and put in another box. 93% sounds like a good usage to me :) # John Bleichert # http://vonbek.dhs.org/latest.jpg To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
