Trying to use startup.pl to reduce the size of httpd child proces
ses....
Hello all,
I am trying to reduce the size of my child httpd processes. We are using
modperl, Embperl, DBI and DBD:Oracle. Our current httpd processes quickly
grow to 22M or so after a database connection. I read in the modperl docs
that modules can be preloaded into the parent httpd process and the child
process will then share the code. I setup a startup.pl file to preload the
modules I need, but instead of reducing the child process size, all httpd
processes are now 22M as soon as apache is started. Modperl is compiled
statically into httpd because dynamic loading has some serious problems on
tru64.
Any help much appreciated,

Yes, of course they are, but now all childs share the same memory, so memory
is taken up only once, while without preloading memory is taken up by every
child. So depending on the number of childs you have, you save a lot of
memory

This is good:

Read up on what's shared and what's not.
