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, --eric
