This issue relates to the following test suite run: https://maloo.whamcloud.com/test_sets/95cf2ada-8f19-11e1-8a98-525400d2bfa6.

The sub-test test_4 failed with the following error:

test failed to respond and timed out

Info required for matching: performance-sanity 4

test_4() {
echo "Large file creation performance"
bash mdsrate-create-large.sh
}
run_test 4 "large file create/open/delete ======"

This test seems very slow, which takes more than 3600 seconds in this test. Usually it only take about 30 mins.

It seems both client are doing this
