Hi! Instaled : FreeBSD 4.0 + Apache 1.3.12 + mod_perl 1.24 + FastCGI 0.52 1) I installed apache with mod_perl - the speed increased.But I didn't understand HOW mod_perl optimizes use of resources and increases speed ? Does it share perl interpreter, script or anything else? 2) Then I installed FastCGI - but I didn't see the differance. Speed and memory usage remained the same. I test with mysql database (16000 records, 5 fields of different types) - SELECT * FROM TEST WHERE one < $a and one > $b; Next, I open, read and parse 5Mb text file. With LWP::Parallel::UserAgent perl module I send 10 parallel requests. Do mod_perl and FastCGI installed in the same Apache server interact and how do they interact if they do at all? Was Lighte!
