Pardon if this is more stackoverflow vs. serverfault. It seems to be on the border.
We have an application that caches a large amount of product data for an e-commerce application using ASP.NET caching. This is a dictionary object with 65K elements, and our calculations put the object's size at ~10GB.
The amount of memory the object consumes seems to be far in excess of our 10GB calculation.
BIGGEST CONCERN: We can't seem to use over 60% of the 32GB in the server.
What we've tried so far:
In machine.config/system.web (sf doesn't allow the tags, pardon the formatting):
processModel autoConfig="true" memoryLimit="80"
In web.config/system.web/caching/cache (sf doesn't allow the tags, pardon the formatting):
privateBytesLimit = "20000000000" (and 0, the default of course) percentagePhysicalMemoryUsedLimit = "90"
Environment: Windows 2008R2 x64 32GB RAM IIS7
Nothing seems to allow us to exceed the 60% value.
