You're creating 14000 arrays, and references to them (refs take up space
too!). That's where the memory is going.
See if you can use a more efficient data structure. For example, it
takes less space to make 4 arrays with 14000 entries
Hi,
thank you all for your hints, BUT (with capital letters ;-)
I think, it's a question of speed: If I hold my data in a hash in
memory, access should be faster than using any kind of external
database.
What makes me wonder is the extremely blown up size (mod)perl uses for
datastructures.
Have you tried DBD::AnyData? It's pure Perl so it might not be as fast
but you never know?

Has anyone implemented a bandwidth limiting mechanism in mod_perl?
Have you looked at mod_throttle?
http://www.snert.com/Software/mod_throttle. There was a thread on this
last week so if you want more information you might read through that.

I have. It does not work under load. At least, three months ago it didn't at
all.

We currently use Apache::AuthCookie for authentication/authorization, and it
works great. However, we want to make a change to how the login works.
In addition to having Apache::AuthCookie intercept requests for URL's that
require auth/authz, we would like to provide a signon area on the main

Hi Andrew,
thanx for the idea to have a look at Apache::ASP. I took that look
meanwhile and to me that seems to be an overhead. Maybe I'm naive, because
it wasn't much more than a glance, but the code copes with things a server

That's pretty good, but obviously not what you were after.

Have that proactive signin area forward to a page behind
Apache::AuthCookie protection and then have that page forward them right
back to where they were? If you don't have frames that would be pretty
easy.

Is there anyway to have the parent apache process log all

recipe 17.5 in the cookbook describes how to do this. basically you can hook

Incidentally, that map statement in your script isn't doing
anything that I can see.
It simulates different values for each record - e.g.:
$line = \t\t1000\t10.99;
@record = split \t, $line;
for ( $i = 0; $i 14000; $i++ )
{
map { $_++ }

How do you use cron to do scheduling, yet calls Apache/mod_perl to

Consider cron does not exist in Win32, maybe an all-Apache solution

Your cron script just uses LWP to call a module running in mod_perl.

The Apache 2 Connection handler opens up the possibility of
using it for all kinds of protocol servers.
However, I have a wild question: Is it possible to use Apache mod_perl

For example, I can use Apache 2 for Telnet, FTP, SMTP,
