We will see how long the following high load average bulk -a configuration survives a build attempt, using a non-debug kernel for this test.
I've applied: # fetch -o- https://github.com/openzfs/zfs/pull/15107.patch | git -C /usr/main-src/ am --dir=sys/contrib/openzfs - 13 kB 900 kBps 00s Applying: Remove fastwrite mechanism. # fetch -o- https://github.com/openzfs/zfs/pull/15122.patch | git -C /usr/main-src/ am --dir=sys/contrib/openzfs - 45 kB 1488 kBps 00s Applying: ZIL: Second attempt to reduce scope of zl_issuer_lock. on a ThreadRipper 1950X (32 hardware threads) that is at main 6b405053c997: Thu, 10 Aug 2023 . . . • git: cd25b0f740f8 - main - zfs: cherry-pick fix from openzfs Martin Matuska • git: 28d2e3b5dedf - main - zfs: cherry-pick fix from openzfs Martin Matuska . . . • git: 6b405053c997 - main - OpenSSL: clean up botched merges in OpenSSL 3.0.9 import Jung-uk Kim So it is based on starting with the 2 cherry-pick's as well. The ThreadRipper 1950X boots from a bectl BE and that zfs media is all that is in use here. I've setting up to test starting a bulk -a using ALLOW_MAKE_JOBS=yes along with allowing 32 builders. This so 32*32 or so potentially for load average(s) at times. There is 128 GiBytes of RAM and: # swapinfo Device 1K-blocks Used Avail Capacity /dev/gpt/OptBswp480 503316480 0 503316480 0% I'm not so sure that such a high load average bulk -a is reasonable for a debug kernel build: unsure of resource usage for such and if everything could be tracked as needed. So I'm testing a non-debug build for now. I have built the kernels (nodbg and dbg), installed the nodbg kernel, rebooted, and started: # poudriere bulk -jmain-amd64-bulk_a -a . . . [00:01:22] Building 34042 packages using up to 32 builders . . . The ports tree is from back in mid-July. I have a patched up top that records and reports various MaxObs???? figures (Maximum Observed). It was recetnly reporting: . . .; load averages: 119.56, 106.79, 71.54 MaxObs: 184.08, 112.10, 71.54 1459 threads: . . ., 273 MaxObsRunning . . .
