I use mod_rewrite extensively on my "main"[1] website. I mean
*extensively*! I find (when everything is working properly on the server,
but that's another story[2]) that mod_rewrite does not appear to adversly
affect performance. For all the shit I have going on[3] to create a single
page, it is a wonder that, even at peak load times, the server can still
spit out a page in under a quarter second.

[2] I had a series of serious serious SERIOUS performance issue events
from March through July of this year. I could not figure out what the
fsck was going on. Finally I updated all the software on the server
(Linux/OS stuff plus Apache and MySQL) and presto! no more server issues.
Wow! Why didn't I update sooner??? (Beacause I am overworked and underpaid?)
[3] mod_rewrite rewrites the URL -- *every* URL -> send to PHP
paginatorizer, go to MySQL database to get meta information, get pae
contents from a file, PHP sews it all together, sptis out an HTML page.
Pretty normal stuff, really, when you are talking about a dynamic
server-side web system, (say, ASP+IIS+MSQL or JSP+Apache+Oracle or
whatever), but still, it is a wonder that all this stuff works so well and
so fast.
