eBay improved parallel efficiency by more than 60%

Posted on Saturday, October 25 2008 @ 18:45:34 CEST by

NetworkWorld reports eBay managed to enhance the parallel efficiency of its servers by over 60 percent this year:
But one tidbit eBay has let slip is that in less than a year, eBay exploited analytics to increase server utilization by more than 1.6X.

What I mean is this: There’s a simple metric called Parallel Efficiency (PE) = (total average server utilization)/(total maximum server utilization). To the extent your parallel efficiency on a parallel cluster is under 100%, you’re essentially wasting server purchase cost, server room floor space, and some amount of power. eBay measured the parallel efficiency of its 10,000+ servers – probably a lot more than 10,000 – and found a figure well under 50%. “Six months” or so later – I’m saying “less than a year” because such timelines are hard to measure precisely – parallel efficiency was up to over 80%. The resulting cost savings are obviously enormous.
