[ale] how do I increase Linux swap file size?

[Ron Frazier]

Jeff,

Thanks for the note.  Several other people said similar things.  My
current RAM is 8 GB and my swap is 8 GB.  See the post I recently did at
around 9:40 PM for some results of some stress testing I did on the
machine.  Bottom line is, I'm leaving it as is.

Sincerely,

Ron

(PS - If you email me and don't get a quick response, you might want to
call on the phone.  I get about 300 emails per day from alternate energy
mailing lists and such.  I don't always see new messages very quickly.)
