Yes, 2 days (7 hours less if I would notice out of disk space). It was that
fast because 5k builds (1/4 of all packages) failed pretty quickly with missing
gcc 😉
* 4x Intel(R) Xeon(R) CPU E7-8860 v4 @ 2.20GHz
* 256 GiB RAM
Actually not all resources have been used, I had 10 koji builders on this
server with 12 CPUs and 16G memory each.
Interesting stuff, I didn't think it would be so fast even given the
dependency failures.
On:
* 16 x Intel(R) Xeon(R) CPU E5-2609 v4 @ 1.70GHz
* 64 GB RAM
it's probably going to take something like 5 or 6 days to mass rebuild
for Fedora/RISC-V (using qemu-system-riscv64).
This is not very comparable however because: (a) we're not recompiling
any noarch packages, we're just copying those in from Koji, and
(b) probably only 20% of the archful packages can be successfully
recompiled at this time.

Thanks,
