Hi DongHyun

The performance difference should not be affected by the order the
gazetteers are read.  I have some random number generators in my
training code, and perhaps various versions of Java generate random
numbers differently.

In any case, differences of 0.05% are not statistically significant,
and I don't want to bother with this.

Peace&Love
