Hi,

i have this ccd:

alice# ccdconfig -g
ccd0            125     0       /dev/sd0b /dev/sd1b
alice# ccdconfig -s
Statistics for ccd0:
        freelist count: 16
        freelist hiwater: 16
        freelist misses: 141401
        ccdbuf allocations: 7889164

It works for some time now but I would not be sad if it would be faster :-)

How do I find out what the fastest settings are?
