Any chance you could do 5-10 runs to get the avg and stddev? May (or may not) prove interesting. 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-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
