Mike, sure
I thought my post title was very clear; couldn't have been any clearer.
I guess i may as well have posted a dancing cat purely for entertainment value.
Perhaps my post wasn't that clear then. Fair enough. I had searched and clawed over tonnes of information. In fact i spent quite a few hours looking. However, it seems not 1 set of parameters is suitable for every nginx + php5-fpm set up, which is sensible really. I'm not a natural sysadmin and as it was the weekend my sysadmin was unavailable, probably off geocaching or something.
What i couldn't find is enough info on how to test and verify my chosen config. Due to the volume of traffic and revenue involved i didnt want it to be trial and error. I also wanted an expert eye cast over the chosen params in case anything jumped out as obviously incorrect.
