perf test 70 takes a long time. One culprit is the output of command perf annotate. Per default enabled are - demangle symbol names - interleave source code with assembly code. Disable demangle of symbols and abort the annotation after the first 250 lines. This speeds up the test case considerable, for example on s390: Output before: # time perf test 70 70: perf annotate basic tests : Ok ..... real 2m7.467s user 1m26.869s sys 0m34.086s # Output after: # time perf test 70 70: perf annotate basic tests : Ok real 0m3.341s user 0m1.606s sys 0m0.362s # Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Reviewed-by: James Clark <james.clark@linaro.org> Cc: Heiko Carstens <hca@linux.ibm.com> Cc: Vasily Gorbik <gor@linux.ibm.com> Cc: Alexander Gordeev <agordeev@linux.ibm.com> Cc: sumanthk@linux.ibm.com Link: https://lore.kernel.org/r/20240917085706.249691-1-tmricht@linux.ibm.com Signed-off-by: Namhyung Kim <namhyung@kernel.org>
