Yeah, I ran into this before - the Ubuntu packages of embree are way slower than Intel's builds. Not sure why; I assume Embree is optimized for the Intel compiler or vice versa. I can add a note to the readme that Ubuntu packages of embree in particular are confirmed to be slow and should be avoided if you want good performance.
I think my Linux x86_64 builds have always bundled an embree .so downloaded from the Embree github, so anyone using the official releases or CI builds of ericw-tools should get good performance.

and with the container compiled version I land on 235 seconds. The same map on Windows runs light on 320 seconds, so some room for improvements there as well.
I did a quick check on Windows of Embree 3.13.5 vs 3.12.2 (both .dll's from Embree's github releases page):
- 3.13.5:
37.1s
- 3.12.2:
37.6s
Didn't do multiple runs, but it seems about the same. So I'm guessing the 235s vs. 320s difference you saw was due to other factors than the embree version - maybe the compiler for the ericw-tools code (MSVC vs Intel on the oneAPI container?), maybe the OS having some impact (?).
I would just update the Embree DLL on Windows anyway, but it's slightly annoying because there's a diamond dependency with TBB (both ericw-tools and Embree depend on TBB) and I have to hunt down a compatible TBB version.
