This patch is trying to make it faster by running the tests concurrently. We provide a new parameter "-j" for the run_tests.sh, which can be used to specify how many run queues we want for the tests. Default queue length is 1, which is the old behavior. Quick test on my laptop (4 cores, 2 threads each) shows 3x speed boost: |-----------------+-----------| | command | time used | |-----------------+-----------| | run_test.sh | 75s | | run_test.sh -j8 | 27s | |-----------------+-----------| Signed-off-by: Peter Xu Reviewed-by: Andrew Jones --- run_tests.sh | 12 ++++++++++-- scripts/common.bash | 16 +++++++++++++++- 2 files changed, 25 insertions(+), 3 deletions(-) diff --git a/run_tests.sh b/run_tests.sh index afd3d95..4d57ff9 100755 --- a/run_tests.sh +++ b/run_tests.sh @@ -13,10 +13,11 @@ function usage() { cat <
