rmem_max and wmem_max

[Eric Kolve <er...@classmates.com>]

I noticed in the modperl guide
(http://perl.apache.org/guide/scenario.html#Buffering_Feature), they
recommend setting rmem_max to a size such that you will buffer all pages
sent from modperl to a proxy in proxy-accelerator mode.  What I am
wondering is, what effect if any does the wmem_max setting have on
this?  I see in the proc fs docs that this is the send socket buffer
size limit, wouldn't modperl be limited by this value? Do you only need
to modify rmem_max?

thanks,
