I don't have the After initially building the caches I get further runs in 2.6 seconds. That's slow, but much faster than 44s and not primarily caused by luaotfload. This was tested with system fonts in Arch Linux. Do you still have the issue also without Please also attach your log file. |

Both files exist on my system, one of them is installed manually from my USB drive (with a large collection of fonts), the other is installed by pacman.

Multiple tests see CTeX-org/ctex-kit#708
in a simple mwe:
It take ~44s to compile and although luaotfload generate font cache, the next compile still need ~44s
