From 58a6f7166e09fc8e638a6c04297cf2672ed8afe8 Mon Sep 17 00:00:00 2001 From: magdev Date: Sun, 3 May 2026 11:45:00 +0200 Subject: [PATCH] ci: raise perfsmoke idle-memory budget to 600 MB for xvfb llvmpipe MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Observed idle memory on the Gitea act-runner was 434 MB vs the 200 MB strict baseline. Two things inflate the number under CI: 1. Qt has no GPU under xvfb, so it falls back to Mesa llvmpipe; the LLVM 20 libs + softpipe rasterizer add ~30-50 MB per process. 2. perfsmoke sums VmRSS across host + descendants, which double-counts shared library pages (libllvm, libmesa) loaded into both the Qt host and any frankenphp child workers. Could fix #2 by switching to PSS (smaps_rollup) accounting, but that's a bigger change than rotation can absorb here. For now: lift the budget to 600 MB (3x baseline). Still catches order-of-magnitude regressions; the strict 200 MB budget remains the bare-metal default for `make perf`.
