If the slowness is due to having to reach over the network for each connection, and mysql having to do a reverse DNS lookup to check through its GRANTs table, then that overhead could very well account for a large chunk of the latency. Switching to persistent connections would make it a one-time cost for the life of the connection.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
