Is there any way to tell if mod_perl is installed in apache? I am using a
shared account. No root access.

You probably can't if if have a shared account. As root, you need to type
type 'httpd -l ' and look for mode_perl.

And you will need to modify httpd.conf, which you probably cant do either.

Try a cheap VPS at www.linode.com or similar.

However, PHP is included in the HTTP header. I thought if Mod_perl is
included, it should say something.

Another idea. Is there a program which will have different results in
mod_perl or none. Then I can test it with this script.

If Apache does not say 'mod_perl' in the headers it is unlikely to be
installed.

You really need root access to configure mod_perl.

I agree. That is one server shows it
2004-10-03 03:41:30.401 Server: Apache/1.3.28 (Unix) PHP/4.3.3 mod_perl/1.28
mod_ssl/2.8.15 OpenSSL/0.9.7c
Another does not:
2004-10-03 03:42:59.700 Server: Apache/1.3.31 (Unix) mod_gzip/1.3.26.1a
mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 PHP/4.3.8
FrontPage/5.0.2.2634a mod_ssl/2.8.19 OpenSSL/0.9.7a
Here is mine:
2004-10-03 03:44:17.782 Server: Apache/1.3.29 (Unix)
However, mine does have PHP, so it is very possible that the Apache is set
up not to say anything about those added headers.

So I am still looking for a script to test it.

Gregory was not giving you an opinion, he was informing you of a fact.
Good of you to agree with the facts though.

Your server does not have mod_perl installed. See how easy that was?

Possible? Sure, anything's possible - including little green men on
Mars. But I won't bet on that, or on your server having mod_perl and not
reporting it.

Why? Just ask your hosting provider, and they'll tell you that you don't
have it.

So what's got your panties in a bunch over mod_perl? Between this series
of posts, and the other ones in the "PHP vs. Perl" thread, I highly
doubt you'll be able to make effective use of it anyway.

It's not a simple matter of just sprinkling your site with some sort of
"magic mod_perl dust" and making it go faster - for any chance at *real*
improvement, you have to write your scripts with mod_perl in mind, and
optimize them to take advantage of the persistent environment.

If it has PHP but not report it, then it is possible for mod_perl too.
In fact, openssl is working but not reported too.

I just want to know if my perl cgi is faster than PHP is because I got
mod_perl or the fact is PHP is still too much slower than Perl regardless of
apache settings.

It's not. As I said, you need to be aware of mod_perl and write your
code specifically to take advantage of it to see any significant
performance boost.

So even if you *did* have mod_perl on your server - and I'm certain that
you don't - you wouldn't be getting any performance gains from it,
because you haven't optimized your Perl code for it.

Quote from http://perl.apache.org/start/tips/registry.html :

"Existing CGI scripts will run much faster under mod_perl."

You can check whether $ENV{MOD_PERL} is set. If it is, your script is
running under mod_perl, if not, mod_perl is not enabled for your
account whether it happens to be installed or not.
