Re: Hardware for poudriere

Hi Bernd,

4 GB is not much for Poudriere builds.  There are two main factors in
play:

 * how many ports you build in parallel
 * whether you set USE_TMPFS=yes

Without TMPFS, I was able to build a lot of ports on my RPi4B+ with 8GB
(same as the one you have), but it really takes a lot of time.  With
four jobs running at the same time and graciously raised timeouts (at
least double, but better quadruple all timeouts or important ports like
llvm and rust will never build), I have built about 1200 ports in 72
hours so far.  That's a long way to having built all of them.

On an x86 box (you can use QEMU to build ARM64 ports there), it's a
lot easier.  I use a Skylake-based server with 8 threads, 32 GB RAM and
the same amount of swap to build the whole ports tree in about a week.
USE_TMPFS=yes makes a critical difference here, but it also causes
significantly higher memory usage for large ports like llvm, rust, or
chromium.  So make sure to keep enough swap around.

Yours,
Robert Clausecker
