you need it working.

I can measure it myself if you can provide me with URLs to your resources
and identify them in terms of which one is mod_CGI and which is mod_perl.
This is the mod_cgi one that works fine, no errors:
http://shevek.kenyonhill.com/cgi/test.pl
This is the mod_perl one (same script) that generates
We can see that mod_cgi bufferizes the output and sends it with
Content-Length HTTP header (to mod_deflate). Indeed mod_perl generates
chunked response. Finally we have the same result. I don't see any problem
at this moment.
Well, the problem is that I get this error in my error_log:

I could upgrade to 2.0.47, but it seems unlikely that it would fix
this. Are you sure you're running a mod_perl without Philippe's fix (in
Apache__RequestIO.h), I assumed he eventually checked it in.
No, Philippe hasn't committed it, neither I have used it. If you can test

I don't know anything about Memoize, but perhap db-level caching would work

When I use Apache 2.0.46, mod_deflate with mod_perl-1.99_09 (or the latest
mod_perl-2.0 CVS), perl buffering is off ($|=1), and my perl script prints
nothing (e.g. 'print ;'), I get the following error:

I used to use mod_gzip under Apache 1.3, and it worked great, saving my
over 50% of my bandwidth for my mod_perl generated pages.
But, it appears that mod_gzip doesn't work with Apache 2. Apache 2 has a
built-in mod_deflate, but I've had some trouble with it (seemed to cause a

That would be of my real interest to know as many details of Bill's
experience with mod_deflate as he can provide.
Since I posted my first message, I've been snooping around the 'net to find
more info on mod_gzip and mod_deflate. Here's what I came up with:
The general recommendation seems to
1. Are you using any Cascaded Stile Sheets and/of JavaScript libraries
linked to your main web pages?
I'm not, but... I think mod_defalte's hook is after all that is processed,
so it's not especially relevant.

I recently moved to Apache 2 + mod_perl2 and things have been working
fairly well.
But, I'm getting an intermittent problem with POSTs where the input data is

p.s. I did find a Rawhide (bleeding edge Red Hat release, I think)
mod_perl-1.99_09, but it doesn't seem to be compatible (I got an error from
Apache).
If I can't find the mod_perl rpm I need, it's looking like I might need to
build it from source. I believe this would mean also building Perl and
Apache from source.
Now, I have a redhat-installed Perl already. From past discussions, the
best idea seemed to be to create a 2nd perl

Thanks for tracking that down.
So, the problem is our tools. For me, that's GTopLimit (but also SizeLimit).
I would think it must be possible to cajole these two into realizing their

There's no such thing as sharing memory between one process on disk(/swap)

the sharing is restored! So, now I'm tempted to run a crontab every 30

This is a good point. I really have no clue how
I just wanted to mention that the theory that my loss of shared memory in

When the lack of sharing occurs, it is correlated with my httpd processes

A number of you indicated that it's likely due to my apache processes being

This is the same problem I've been struggling with.
What has fixed it for me is building Apache and mod_perl from the tar
archives and linking Apache statically (no .so's).
I haven't investigated much further, but even after I built Perl, Apache,
and mod_perl by hand it still happened. Only
