Below the probably quite uninformative results, run under Linux with 2.2.16
on an AMD K2 350Mhz with 256MB RAM, EIDE HDs and other run of the mill
hardware.
I suspect some of the normal system jobs which usually run during the night
caused the wildly varying results. Whatever else, for my purposes at least
any performance issues with differening NAMEDATALENgths are nothing much
to worry about.
NAMEDATALEN: 32
220.73 real 3.39 user 0.10 sys
110.03 real 2.77 user 4.42 sys
NAMEDATALEN: 64

109.76 real 2.53 user 4.18 sys
NAMEDATALEN: 128
