Yes, but I can't for the life of me figure out why it's so damn important
to avoid. ;)
Here's a common example:
There exists a 400 mhz Pentium II single-processor with 64 Mb of memory
running Redhat Linux. Running on the server is ftpd, httpd, telnetd,
smptd, dns, a stock Diku mud server, a DGD LP mud server, and a ColdMUD
server. The server is probably underloaded.
Is there context switching going on here? YES! Loads and loads of the
"expensive" process-level context switching.
<rant>
Now suppose I wish to redesign and multi-thread that Diku mud server.
Why would I WORRY about the overhead of "cheaper" thread-level context
switching?
Why should I CARE at the application-level how many processors are
present on the friggin box!?!@#!??
</rant>
