Given that there is no actual useful/hard data in the above the chances 
of there being a relevant answer in return is doubtful.

Also given your subsequent post the major version you are using is 
nearing 1 year past EOL and is 21 minor releases behind the last release 
in the series. At the very least you need to bring it up to the last 
minor release.
