dt 2.7 still facing some performance issues

:slight_smile:
As I said above, I did that due to compiler clustering. With native the code cannot run on other CPUs.

  • I changed to -march=native -O3 now and omitted -gddb (yes, a bit faster, but less than I thought)
  • this was used just the recent few days, beforehand I used build.sh
  • regardless which way, I have that lag, when I touch WB for the first time and fluent after 2nd touch…
