I'm using mod_interchange. I'm not sure it's that much of a
performance boost. What it saves you is the instantiation time of the
t/vlink executable. I guess it's removing a layer out of the
communications as well. I think it simplifies security (no setuid cgi
scripts). IMHO it makes the setup of apache cleaner. It's much more
obvious what you're doing in the httpd.conf when you setup a directory
as interchange-hander instead of just generic ScriptAlias.
But, don't take my spin on performance as gospel. I've not done any
benchmarking (in fact, I don't know how to benchmark web apps).
However, originally I was trying to run IC on a sparc IPX (a 40MHz
plain ol' sparc chip) with 64MB RAM. It was very slow. I switched
over to mod_interchange hoping it would buy me _something_. It did
get me some performance gain (just because instantiating a new
interchange process was so heavy for that box). My page load times
went from 30 seconds per page to about 20 - 25 seconds per page. It
wasn't enough to let me stay on that box!
As I said, this isn't a benchmark. I doubt if you have a dual pentium
box with 128MB+ RAM you will see a 33% gain in performance. Anyway,
you asked for anecdotes and I'm giving you mine. :)
