I just recently upgraded a rails app of mine to run on edge (and the
1-2-pre-release branch) and I noticed my fcgis required roughly 6-8MBs
more memory after just a couple requests.
For example, each fcgi on edge would start around 40MB and rise to
~46MBs after a couple requests.
I downgraded my app back to 1.1.6 and each fcgi would start at around
33MBs and rise to ~38MB.
As a result of the increased memory requirements, my app can no longer
be run on TextDrive using edge since they have a max resident memory
cap of 48MBs which I would quickly hit (and they just kill your fcgi
when you do).
Is this increased memory requirement to be expected?
I would be happy to give you more details about my setup if you think
it may have an impact on why the memory usage is so high in my case.
