<p class="MsoNormal">We just built a Supermicro server with 3 LSI 9300-8i HBAs and 12 2 TB hard drives and are concerned about slowness after running a postgres benchmark. We also ran this benchmark on an HP Proliant 380 G9 with 14 disks and on a Sunfire server
running OmniOS as well. The results showed the HP Proliant being many times faster (orders of magnitude) than the newer Supermicro server and the Sunfire.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any ideas why the HP is so much faster? It just has one Smart Array Controller which I didn’t think would be faster than JBOD<o:p></o:p></p>
