This comment is probably more about Oracle than about Solaris as such. IIRC, there was also a time when Oracle partnered with HP and a joint selling point was that Oracle ran fastest on HP-UX. I can't seem to find a link for this. Later, there was also a bitter fight and a lawsuit between the two companies on Oracle dropping support for Itanium based machines from HP.
