That's super informative, as I wrote my methodology was flawed and indeed... Tests to redo. Btw what's the reason for this terrible regression?

- justinsaccount 9y agoThe regression being the drop in performance you saw? I don't know.. I'd be interested in seeing what the performance looks like on multiple "identical" C4.X8LARGE instances, regardless of KPTI. If you mean their results.. they actually show an increase in perf in later kernel versions. Based on https://github.com/phoronix-test-suite/test-profiles/tree/master/pts/redis-1.0.0 https://github.com/phoronix-test-suite/test-profiles/tree/ma... it looks like they just use the default configuration and run the benchmark with -n 1000000 -P 32 -q -c 50 --csv
