Man, if I were the OP I'd be naming names, and letting the idiots at
INSERT MAJOR VENDOR HERE know that I was naming names to the whole of
the postgresql community and open source as well to make the point that
if they look down on open source so much, then open source should look
down on them.
PostgreSQL is open source software, BSD and Linux are open source / free
software. bonnie++'s licensing shouldn't matter one nit, and I'd let
everyone know how shittily I was being treated by this vendor until
their fixed their crap or took it back.
Note that if you're using fibre channel etc... the problem might well be
in your own hardware / device drivers. There are a lot of real crap FC
and relative cards out there.
