I had a look at the memory usage of my apache/mod_perl 1 processes, and was alarmed to find that only 3Mb of 25Mb processes was being shared (and that's straight after startup)
I have gone to great lengths to
(1) Preload modules in my startup file
(2) Load shared config data during server startup so that that info can also be shared
i've pulled everything out and started adding it back in, and it looks like nothing much gets shared other than the perl interpreter.
When I load nothing, the size of my processes starts at 4204 (2504 shared) . When I load everything, the size rises to 17144 (3920 shared) - not much is being shared...
Am I being really dumb here? What am I missing?
thanks
Clint
