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.
