On a Razen 9 7900, kernel-doc takes about 32 seconds. It should be noticed that kernel-doc doesn't run in parallel. Python still suffers for a global big lock (called GIL). My attempts to run in parallel actually made kernel-doc slower, but this is changing: the next Python version is planning to get rid of GIL. So, maybe within a year we can re-add the patches to run it in parallel. > and produces a bunch of warnings with current mainline it seems.
