ufs multilabel performance

Dear List,

I've noticed that when I enable multilabel on an fs, a file creation gets
around 20-30 times slower than without multilabel set.

This one-liner can be used to test the differences:
$ truss -D perl -e 'open(F, ">$_.file") for 1 .. 1000'

And one can see that the open call takes much more when multilabel is set
on an fs. It seems that only file creation needs that many time, when a
file exists it is opened much faster.

Could someone acknowledge this, and have some suggestions how to make it
