Visualize Whirled Peas ...

That's the view of today taken at about 7pm. The load average on the server hosting Wampum (and nothing else) was in the mid-60s for part of the 4 o'clock hour (EDT). Our normal load is about 1 and change. For those of you who know what this means it is a dual processor (996.85-MHz 686-class) node w/1GB of RAM and two ST318437LC (all the load inelegantly on one partition of one drive), and about 65 perl5.8.8 processes and the same number of httpd (2.0.55) processes, and a 4.1.18 mysqld process.

We are cpu bound here, not b/w bound (that bill will fall due soon), unlike '04 when we were b/w bound. Its an ad, in a sense, for MT 3.2. Just for completeness, when we hosted Alas A Blog and Barry's blog was targeted by a ddos (several hundred attack nodes doing an ad insertion campaign made _much_ worse by MT's then-foolish-anti-comment-spam dorkage), the load average went to about 100 w/o crashing the host.

Why people engage in synchronous behavior is beyond me, I can't even get myself near a mall after Halloween, but it does make for interesting system load mix and performance data.

Perhaps most people eat dinner at around the same time, which would free them up to use the Internet at around the same time. Regardless of their 3D shopping habits.
