compute-1-4 back up; compute-1-7 went from worst to best in rack 1

I replaced compute-1-4’s power supply. I also replaced compute-1-7’s innards. It was a 2.16Ghz Core 2 Duo with 4GB of RAM. It is now a 3.1Ghz octa-core Phenom with 16GB of RAM. Cost for this upgrade: ~$400. I’ll be “benchmarking” it shortly (with dnetc, not a real benchmark, but might have something to do with something).

    compute-1-7 before upgrade: around 50Mnodes/sec

    after: 150MNodes/sec. Nice! Tripled the speed…

    Hm. But it should have quadrupled… because I quadrupled the number of cores. So that means that a single core of this chip is actually slower than an E6400 core? Humph. I guess people do say this about modern AMD processors….
