45MB x2 is a lot less than 215MB...
Also, I would expect the actual consumption to be less than 2x since not
all the data will be doubled in size..?
Any other suggestions on how to debug this 5x jump in memory usage?
Thanks

Hi
I am trying to figure out expected memory usage of PHP
Under my 32bit install Apache 2 processes are drawing around 45MB
virtual and 25MB RSS. (XCache enabled)
However, under 64bit, same PHP and Apache versions, FastCGI is consuming
around 110MB virt and 25MB RSS. However, Apache2 processes are
consuming around 215MB virt and 20MB RSS
Can anyone please help debug why the virtual consumption is so high?
Actually the RSS numbers look fine - it's the vsz numbers that I am
trying to understand why so high?
Thanks
