PostgreSQL 9.3 benchmarks

[Raimundo Santos]

Hello all!

Just to note: I have seen an annoying bug with FreeBSD in Gigabyte and
Intel motherboards with Intel processor Core i5 and i3 and USB 3.0.

When I remove the monitor from D-Sub or DVI connectors, XHCI drivers got to
hundreds of thousands of interrupts/sec and stays there. Need reboot to
stop it. Like this: http://www.freebsd.org/cgi/query-pr.cgi?pr=179376.
Could reproduce in FreeBSD 10.0 too.

But my hardware, what can I say, is cheap hardware.

Fracois, have you removed a monitor from the test machine (this is really
strange to ask, I know)? Motherboard has USB 3?

May this behaviour interfere with VM faults?

Best regards,
Raimundo Santos
