These Xeon 5600s are fast

I purchased a new single cpu Xeon X5670 (6 core!) application server and diverted a bunch of our load to it just to see how it performs.

The new machine is currently handling 50% of our load without breaking a sweat, and our average response time has improved by 20 milliseconds. This traffic was previously handled by 2 x Xeon 5300 machines (8 cores each) that are over 3 years old. I don’t have enough memory in the new box to figure out how much it can handle before performance starts to degrade – I’ve only got 6 GB in it at the moment due to a build mistake.

Two of these $3000 half-depth single CPU servers could easily run the entire Rails part of the site (Three for redundancy and breathing room)

Here are the specs. It’s an application server so the only disk is a smallish SSD:

  • 1 x Xeon X5670 Six-Core 2.93GHz, 12MB Cache, 6.4GT/s QPI
  • 12GB RAM (3 x 4GB) @ 1333MHz Max
  • 80 GB Intel X25-M SSD
  • Power consumption: 1.0 amps (208V)

Normally I load up with as much memory as is reasonable, but this CPU offers the most performance with 3 DIMMs per CPU. At least I’ve got plenty of memory to spare now that those older servers won’t be running Rails anymore.

    Great update as always. What kind of impact does the SSD have that you’ve found? I’ve been really curious about that lately.

    Hey Jeff,

    I actually haven’t done any testing with SSD performance on my app servers. The difference is noticeable during a deploy but other than that, there isn’t really any disk IO on these machines.

    I chose the SSD so that I could buy a smaller, cheaper half-depth machine with no hotplug, no RAID and only one drive bay. I’ve never had a reason to have any amount of storage in my app servers but before SSD I was doing RAID setups because hard disks fail too often. Going with the SSD and single drive chassis saved me about $400.

    help!! Google-analytics freezes my cpu. Have had to resort to numerous work arounds, but really, Ravelry is nearly unusable for me as well as every other site that uses google analytics.
