Re: [knot-dns-users] Excessive memory usage - knot 2.6.5

For a first idea of usage I'd choose the "resident set size" measure - either VmRSS (current) or VmHWM (peak).  (I'm assuming no noticeable swapping happens here.) For Knot-DNS itself, there have also been some improvements in memory usage since 2.3.4 IIRC, but I don't know details there (Dan should know best). --Vladimir
