Hi, i have a question regarding mod_perl/apache
mysql memory usage
I have a Linux box running Red Hat 6.1, Apache
1.3.14,
compiled statically with mod_perl 1.24_01, mod_ssl, and Open SSL, mod_dav and mod_gzip running as DSO's, MYSQL is mysql-3.23.28-gamma-pc-linux-gnu-i686 (binary) im using Apache DBI and Apache Session Mysql the linux box has an Intel celeron processor @400mhz, 96 Mb of RAM (graphics video share at 4MB i think) and a hard drive of 4GB this is a development offline server so i running things like X, and, vnc and kde but im very concerned with the usage of memory im connecting via ethernet from a windows box with Internet Explorer and with Netscape, after a few requests httpd memory usage grows to 80MB, and mysqld to over 20MB it still feels fast but im wondering if its normal??? i m not familiar linux memory usage under
linux
, i know that probably this question should be sent to other list any suggestions to where?? anybody please could tell me where to look (my
mason components, handler.pl,
httpd.conf, or somewhere else) i guess that the same mysql database handle isnt being used by the components am i right? im using Mason 0.896
