During the recent staging cycle, I noticed a huge number of SBCL build failures, especially when emulating aarch64 on x86_64. > I diffed the CI build log output with my local > attempt and got the same thing modulo timings > [1] and other harmless stuff. > > [1] the Odroid N2 looks roughly 3x faster than the CI > on this specific build / test (total 30 mins vs 90). If it was an emulated build, that's more or less expected. The emulation is very slow. Comparing the Overdrive 1000 (4 x Cortex-A57, 25 watts TDP) to the Odroid N2 (4 x Cortex-A73 and 2 x Cortex-A53, only 5 watts TDP), I'd guess the Overdrive will complete the compilation more quickly, despite the older design and lower core count. I'm retrying the build now on one of the Overdrives.
