perf test java symbol: Remove needless debuginfod queries
Test case 'Test java symbol' might run for a long time. On Fedora 38 the run time is very, very long: Output before: # time ./perf test 108 108: Test java symbol : Ok real 22m15.775s user 3m42.584s sys 4m30.685s # The reason is a lookup for the server for debug symbols as shown in: # cat /etc/debuginfod/elfutils.urls https://debuginfod.fedoraproject.org/ # This lookup is done for every symbol/sample, so about 3500 lookups will take place. To omit this lookup, which is not needed, unset environment variable DEBUGINFOD_URLS=''. Output after: # time ./perf test 108 108: Test java symbol : Ok real 0m6.242s user 0m4.982s sys 0m3.243s # Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Heiko Carstens <hca@linux.ibm.com> Cc: Ian Rogers <irogers@google.com> Cc: Leo Yan <leo.yan@linaro.org> Cc: Sumanth Korikkar <sumanthk@linux.ibm.com> Cc: Sven Schnelle <svens@linux.ibm.com> Cc: Vasily Gorbik <gor@linux.ibm.com> Link: https://lore.kernel.org/r/20230509131847.835974-1-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
