Dual Core Linux Performance: Two Penguins are Better than Oneby Kristopher Kubicki on July 1, 2005 5:55 AM EST

With all of the attention on dual core processors lately, it has been real easy to overlook the one application that might benefit more from multiple cores than any other; Linux. OK, so technically Linux isn't an application, but the kernel has supported SMP for nine years almost to the date. The road to SMP has not been an easy one for Linux, but in the last nine years, and particularly since 1999, Linux has received quite the attention as a 2-8 processor core operating system. If you need a reference, just look at how many Linux machines hold SPEC benchmark records in web serving and number crunching.
But does any of this translate to great desktop performance for dual core processors? We are going to look at that question today while also determining whether Intel or AMD is the better suited contender for the Linux desktop. We have some slightly non-traditional (but very replicable) tests we plan on running today that should demonstrate the strengths of each processor family as well as the difference between some similar Windows tests that we have performed in the past on similar configurations. Ultimately, we would love to see a Linux configuration perform the same task as a Windows machine but faster.
Just to recap, the scope of today's exploration will be to determine which configuration offers the best performance per buck on Linux, and whether or not any of these configurations out perform similar Windows machines running similar benchmarks. It becomes real easy to lose the scope of the analysis otherwise. We obtained some reasonably priced dual core Intel and AMD processors for our benchmarks today, and we will also throw in some benchmarks of newer single core chips to give some point of reference.
