Hi mike, We found that, in case of write through caches, the test results were consistent for all caching solution with EnhanceIO providing better throughput in comparison to bcache and dm-cache. However, under write-back mode, dm-cache showed a large standard deviation. The results for EnhanceIO and bcache were consistent with EnhanceIO providing higher throughput when compared to bcache. We have performed 5 runs for all our performance tests and observed their mean and standard deviations. The test results can be found at: https://gist.github.com/sanoj-stec/5858574 The test scripts can be found at: https://github.com/stec-inc/EnhanceIO/tree/master/performance_test Regards, Sanoj -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
