There sure are lots of options J

Does the perl implementation use a single persistent embedded interpreter or does it spawn a new interpreter per request?

Things like persistent database handles come to mind.

Performance would be drastically impacted if it were to spawn new interpreter per request.

Any ideas?

oh yeah, i forgot about those too.
python,perl and lua can all do that.

What about a mod_perl XML binding like the example here?

Would this be faster than a setup like

mod_curl_xml -> lighttpd -> FastCGI/Perl  ?

I guess it would depend on if mod_perl in FreeSWITCH spawns new interpreter per request
or if it uses one interpreter instance with multiple threads to execute pre-loaded perl.

Anyone know if this is the case?

May be not the best way, but very simple.
Well, it depends on what you have to do, but "directory" serving based
on DB queries (this what I'm using it for) is very simple - just few
lines of code.

I should say I have no idea how hard is to write custom FreeSWITCH
module (may be I should try it :-), but the FS code is very nice!

:-) Yes, you are right. And as a bonus some CPU utilization...

Like I wrote above, I didn't say it is faster, but IMO it is very simple
and not as slow as it looks (when using apache + php + apc).
