[sf-lug] SF-LUG mbox archive rsyned ~overnightly

[Michael Paoli]

And, as far as I know, other than what Rick backs up of
linuxmafia.com
I think I'm the only one that backs up SF-LUG's list (at
least mbox archive & roster).

Anyway, slight tweak to the mbox backup.
Most notably, since due to ISP changes, both myself (@home) and
linuxmafia.com have fair bit higher bandwidth now.

So, upped the bandwidth limit on the rsync:
$ cd ~/bin

increased --bwlimit= from 5 (KiB/s) to 312 - as both client and server  
have significantly more bandwidth now (due to ISP changes); and that  
312 should still be <~=1/2 least nominal available bandwidth (so  
should generally not come near to saturating any network bandwidth  
involved)

Oh, also, I left --compress-level=9 ... did 'bit 'o testing, that
seemed (and actually was) fastest in net (and when done without
bandwidth limit), though the differences between --compress-level=5
through --compress-level=9 were about down in the noise levels (and
didn't test enough to definitively tease 'em apart - if that would
even be doable).  When I did tests, I also mostly randomized the
ordering, so as to mostly (and especially after first) offset any
speed advantages from caching, and also mostly randomize any other
"noise" elements.
