It will create a lot of confusions to people. Why then the mysql provides such a controversial parameter? So this is a dead end? It will create a lot of confusions to people.

My dedicated server running a couple of scripts which heavily rely on database (Search engine and a social websites) My CPU chart shows MySQL as consuming 57% of the processing power which is too much especially that the sites are still under development (Cosmetically) with number of visitors not exceeding 1500 per day. Looking to solve this problem I came to know about sort_buffer_size and few more things. Anyway and by a total fluke I decided to upgrade MySQL from V5 to V5.1 as it was glaring before my eyes in WHM control panel. I clicked to upgrade and that was all. The easy one, Unattended upgrade. Now the load is 6% only just like magic! The sites are still as responsive as they used to be. I hope this helps even though it won't add anything from a technical point of view. Hi All,

It really is all good. Spent valuable time reading due to excellent responses, incl xaprb's. All I knew it's per session default 2 mb.
