Thanks, Ed. The mod_perl performance tuning guide says that this copy-on-write is normal behavior: http://perl.apache.org/guide/performance.html#Sharing_Memory But, it still seems that share is being lost fairly quickly on my server. I don't know what happens under the covers in Embperl, Perl, mod_perl or Apache, really, which is why I brought this up here, just in case someone could say "No no no, you're doing this all wrong"... If the dropoff in shared memory to this extent is "normal", then I'll live with it. Otherwise, it's an interesting scaling issue with this architecture. I wonder if Apache 2.x will handle this any better with threads. No idea how all that works on Linux...
