Hi Anton, You are likely hitting a known problem, see thread "performance regressions in 15.0". E.g., just picked one mail saying what I also personally think about it: https://lists.freebsd.org/archives/freebsd-current/2025-December/009623.html (arguably, some RAM factories have burnt out for retail consumers since then...)
AFAIK, the default was never switched back, but if you're building from source, a new knob was added to recover the previous behavior, see: https://cgit.freebsd.org/src/commit/?id=8d5a11cd0137d3ad Thanks and regards. -- Olivier Certner
