Of course. But I'm a laid-off engineer. If you like, I'd gladly take
donations for more RAM. In the meantime, this machine remains 256M.
This is a single-user desktop with no external access servers
like SSH, Apache, or NFS running. I have a firewall to enforce
no external access, which "stealths" all ports except the e-mail
port, which is denied.
I find that on my machine, memory usage often looks like this:
Mem: 248088k total, 244192k used, 3896k free, 11860k buffers
Swap: 524120k total, 182916k used, 341204k free, 43576k cached

Thanks for the reply.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
