I had the thought that I should be able to get similar results as your "8x-SKYLAKE-UMA" on my test computer, i7-2600K. Or that at least it was worth trying, just to see. I couldn't find the same or similar test on Phoronix, and my attempts to do similar, for example, with iperf, didn't show differences between the baseline kernel and one with the teov6 patch. So I tried the test set you referenced [1]: On 2018.12.01 06:18 Giovanni Gherdovich wrote: ... > * netperf on loopback over TCP > * global-dhp__network-netperf-unbound I assume this means that I am supposed to do: cp config-global-dhp__network-netperf-unbound config from the configs directory. Anyway that config file looks correct. Then: ./run-mmtests.sh --no-monitor 3.0-nomonitor ... > * sockperf on loopback over UDP, mode "throughput" > * global-dhp__network-sockperf-unbound Similarly (from the appropriate directories): cp config-global-dhp__network-sockperf-unbound config ./run-mmtests.sh --no-monitor 3.0-nomonitor My issue is that I do not understand the output or how it might correlate with your tables. I get, for example: 3 1 1 0.13s 0.68s 0.80s 1003894.302 1003779.613 3 1 1 0.16s 0.64s 0.80s 1008900.053 1008215.336 3 1 1 0.14s 0.66s 0.80s 1009630.439 1008990.265 ... But I don't know what that means, nor have I been able to find a description anywhere. In the README file, I did see that for reporting I am somehow supposed to use compare-kernels.sh, but I couldn't figure that out. By the way, I am running these tests as a regular user, but they seem to want to modify: /sys/kernel/mm/transparent_hugepage/enabled which requires root privilege. I don't really want to mess with that stuff for these tests. > [1] https://github.com/gormanm/mmtests Can you help me to produce meaningful results to compare with your results? ... Doug
