LOL, today I did some testing with NanoPi NEO, kernel 4.7.2 and the new schedutil cpufreq scheduler. I let the following run to check thermal readouts after allowing 1200 MHz max cpufreq: sysbench --test=cpu --cpu-max-prime=20000 run --num-threads=$(grep -c '^processor' /proc/cpuinfo) To my surprise the result was just 117.5 seconds -- that's 'better' than RPi 3 with same settings and with Orange Pi PC while being clocked higher (1.3 GHz vs. 1.2 GHz) I got the following a few days ago: 'sysbench takes 142 seconds, H3 constantly running at 1296 MHz, SoC temperature reached 74°C but no throttling happening'   Wow!!! An increase in performance of ~30 percent just by using a new kernel! With a benchmark that should not be affected by the kernel version at all?! That's magic.   So I immediately tried out our 3.4.112 Xenial image. Same thermal readouts, same result: 117.5 seconds! What did happen?   I tried out Xenial 16.04 LTS with both 4.7.2 and 3.4.112 kernel. And before I always used Debian Jessie. Ok, downloaded our Jessie image for NanoPi NEO, executed the same sysbench call and got 153.5 seconds (which is the correct value given that no throttling occured, max cpufreq was at 1200 MHz and OPi PC clocked at 1296 MHz finishes in 142 seconds!)   What can we learn from this? Sysbench is used nearly everywhere to 'get an idea about CPU performance' while it is horrible crap to compare different systems! You always have to ensure that you're using the very same sysbench binary. At least it has to be built with the exact same compiler settings and version! We get a whopping 30 percent performance increase just since the Ubuntu folks use other compiler switches/version compared to the Debian folks:   This is 2 times 'sysbench 0.4.12'   Ubuntu Xenial Xerus: root@nanopineo:~# file /usr/bin/sysbench /usr/bin/sysbench: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/, for GNU/Linux 3.2.0, BuildID[sha1]=2df715a7bcb84cb03205fa3a5bc8474c6be1eac2, stripped root@nanopineo:~# lsb_release -c Codename: xenial root@nanopineo:~# sysbench --version sysbench 0.4.12 Debian Jessie: root@nanopineo:~# file /usr/bin/sysbench /usr/bin/sysbench: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/, for GNU/Linux 2.6.32, BuildID[sha1]=664005ab6bf45166f9882338db01b59750af0447, stripped root@nanopineo:~# lsb_release -c Codename: jessie root@nanopineo:~# sysbench --version sysbench 0.4.12 Just the same effect when comparing sysbench numbers on RPi 2 or 3 when running Raspbian or Ubuntu Mate -- see post #12 above (but there the difference is only 15 percent so it seems either the Raspbian people aren't using that conservative compiler switches compared to Jessie or Ubuntu Mate for Raspberries does not optimize that much as our 16.04 packages from Ubuntu repositories)   TL;DR: Never trust any sysbench numbers you find on the net if you don't know which compiler settings and version have been used. Sysbench is crap to compare different systems. You can use sysbench's cpu test only for a very limited set of tests: Creating identical CPU utilization situations (to compare throttling settings as I did before in this thread), running tests to estimate multi-threaded results when adding/removing CPU cores or test CPU performance without tampering results by memory bandwidth (sysbench is that primitive that all code runs inside the CPU caches!)   Everything else always requires to use the exact same sysbench binary on different systems to be able to compare. So no-cross platform comparisons possible, no comparisons between systems running different OS images, no comparisons between different CPU architectures possible. Using sysbench as a general purpose CPU benchmark is always just fooling yourself!
