Performance

[Randal, Phil]

Max Children = 2
Max Unscanned Messages Per Scan = 10
Max Unsafe Messages Per Scan = 10

These seem a bit on the low side to me.

The defaults are:

Max Children = 5
Max Unscanned Messages Per Scan = 30
Max Unsafe Messages Per Scan = 30

Any reason why you so drastically changed them downwards?
