I’m having an issue with, what I consider high memory usage, on a ExpressionEngine v2.5.3 install. This is a recent EE1 – EE2 upgrade if that makes a difference.
An empty template on this project uses 10MB of memory. I tested on another v2.5.3 project and an empty page there is using 2MB of memory. I’m seeing 30+MB usage on normal templates and frequently the browser loses its connection to the server.
Is an addon causing this increased memory usage? What’s the best way to track this backwards?
The install is definitely acting up after this upgrade.

It seems the answer to my question is ~9MB is a normal starting level for a blank template on an EE install.
The template which starts at 2MB is on an EngineHosting VPS/VSC account with APC bytecode caching enabled, hence the difference in numbers.
