[conspire] The difference Apache tuning makes

Someone mentioned at the CABAL meeting that he'd been unable to get a
response from my Web server.  I got around to investigating, in part
because system load had been absurdly high (40-50) during the prior week.
This morning, I finally got around to tuning performance-related
values in /etc/apache2/apache.conf.  Killed the Web server, restarted.
Tweaked it a bit.

I think we're back to normal.  Note the progression in load values,
starting a few minutes after I re-tuned Apache httpd:

$ uptime
 09:55:56 up 87 days, 18:36, 14 users,  load average: 37.70, 36.49, 36.71
$ uptime
 10:12:56 up 87 days, 18:53, 14 users,  load average: 9.13, 7.92, 18.50
$ uptime 
 11:43:02 up 87 days, 20:24,  7 users,  load average: 1.76, 1.97, 4.61

A load of around 1-2 (which is where things appear headed) is a lot more
like it.
