Greetings, Correct me if I m wrong. For in-core web server , every copy of server loaded has the perl and/or php in it. For modules, its a shared library, the server is smaller size, and only a copy of the module is loaded in memory. However, in-core is slightly faster then modules, IIRC. I remember reading the performance pages of mod_perl, they recommend running mod_perl in-core servers separately as a application server. Thats my understanding of the difference between in-core and modules. Regards, /calvin lines with :> are quotes from Mike Meyer's email :> Karsten W.
