darktable flatpak running slower than deb install

Software darktable
15

For darktable -d perf this is what I’m getting
darktable -d perf.txt (9.1 KB)
But on `flatpak run --command=darktable -d perf org.darktable.Darktable I’m getting this “error: Invalid id darktable: Names must contain at least 2 periods”
