Ticket #7598, comment 5
v2 v3 1 I agree that encoding with tiles is still preferred for decoding performance ([ data https://docs.google.com/spreadsheets/d/1AO3lDZnpC8pNJffOknY1rIxXwLog_ISwHhO_sv3Xlhg/edit#gid=1957344704]). But with `-tile-columns 1` the CPU spiked at 32% usage, while with `-tile-columns 2` and `-tiles 2x2` the max CPU usage was 53%. More than 4 tiles is not necessary to reach great decode performance, so `row-mt` could still provide a big speedup in encoding performance.1 I agree that encoding with tiles is still preferred for decoding performance ([https://docs.google.com/spreadsheets/d/1AO3lDZnpC8pNJffOknY1rIxXwLog_ISwHhO_sv3Xlhg/edit#gid=1957344704 data]).
