Sweeeeeet! :-)
TBH the only reason I brought it up was that we had a similar question on
one of the FreeBSD lists. Where they had difficulty exceeding 96 on a 128.
I've forgotten whether it turned out to be config of (actual) limitation.
Mind you that was BSD. But given the shared heritage, it seemed an
appropriate question.
Thanks for the stats. Maybe I should give Fujitsu a look. :-)
