I'm not sure you did anything wrong, but your results are very different from what other people have reported. In general, because perl threads don't actually share anything (except opcode trees) unless you tell them to, all the data gets copied to each thread, which ends up taking up more memory than the prefork model with COW. Maybe you have the PerlInterp* settings set low so that you actually have fewer interpreters running than you did when you were running prefork? If so, that's similar to using prefork with a reverse proxy in front. - Perrin -- Report problems: http://perl.apache.org/bugs/ Mail list info: http://perl.apache.org/maillist/modperl.html List etiquette: http://perl.apache.org/maillist/email-etiquette.html
