Has anyone tried bonding two gigabit ethernet cards in the server?
Wolfgang, I think, suggested using tmpfs instead of a RAMdisk. It works
the same, except that it will grow and shrink according how much you put
into it. By default it will max out at using half of your RAM; if you
have a local hard drive for swap, you can increase that up to the total
of RAM and swap space, less a margin (say 32MB).
