Well it does take time to startup another pg process, it's just a tiny
amount of time with your current utilization. Sometimes a few miliseconds
can add up (say if you were spawning many processes per second).. Still,
you're right, it doesn't look like persistant connections are going to offer
you much increase in performance so I wouldn't bother.. Note that I've
*alway* had problems getting them to even work correctly with PHP --
supposedly things were fixed in alter 4.0.x releases but I've not tested it
much to say for certain.

That's a pretty common misunderstanding about what persistent conenctions
are, no worries..
