Yes? GCC is slow to compile
Looking att my last build using Poudriere but this box runs 9 workers with 8 jobs each at the same time (E5-2683 v4 @ 2.10GHz, 16 cores)

It seems to work in this defined way when using less than 20 core (variation is due to hyperthreading)
But with 20 cores it has now already over 80 hours.

The maintainer says this is normal, because with more cores it does compute harder to get better optimization.
What I do not understand is how this aligns with reproducible build: when the resulting binary must be the same in either case, what is the point in consuming more cpu to obtain the same result?
 
You might try disabling LTO for that package. It takes three times as long to compile when enabled. I did disable LTO for some time. Made a new install. And did not bother to disable again. But in use I cannot feel any difference when enabled, except for the longer compiletime for gcc :)
 
We don't have reproducible builds in ports (yet) and there seems to be something odd going on with your system.

It's not the question if we have them, the question is if gcc12 supports them. I agree that something odd is going on.

And sure I could switch off the LTO, as there is probably no benefit from it. but then this is a dedicated builder node, and I'm fine with the usual four hours duration.
Now let's find out if this one will ever complete...

I'm putting a big question mark on this claim.
