However, if you plan to have, say local and remote X, VNC, I'd add ~2GB the mix. Swap: Always setup some kind of swap - at-least 1-2GB. Disk space is cheap, but if you somehow miscalculate the amount of memory your application needs - even by 5% - the lack of available memory will trigger the OOM killer. (Which tends to produce problematic results... such as killing sshd and getties [happened to me once...]) In general, I usually setup 2-4GB swap on desktops, and 8GB of workstations/servers. E.g. I'm typing this on a dual Xeon workstation with 8GB of memory and 8GB of swap and less than 71M of swap is being used. - Gilboa -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
