this paper,we describe the experimental optimization of Linux kernel on a NUMA machine for commercial workloads.For the evaluation,we used a small-scale NUMA machine which consists of two nodes total of four processors.Two kinds of benchmark programs were used for the measurements,each models WEB server execution or application server execution.We measured the OS function execution timings by a kernel profiler and also measured the memory access statistics by a hardware bus tracer.By using these data, we analyzed the execution characteristics of the programs.The experimental results showed the overhead of the NUMA machine is mainly in OS,and the OS execution time can be reduced 18%--20% by the memory access localization for these benchmark
