In order to asses any performance differences when switching Modeshape to 3.7.1 which a couple of tests were conducted.
Modeshape 3.7.1 fixes the issue with large file ingests we were seeing, therefore adopting this version is crucial for Fedora 4.
Summary
The performance levels were quite stable and the avg decrease of 1.61 % in the six different tests is well within error tolerance.
