# Original measured times of the whole test case before

# export LVM_TEST_PVS=300

# make check_local ~52sec (U:29s, S:13s)
#
# With patch from 2015-03-06:
#
# make check_local ~30sec (U:10s, S:12s)

# TODO: extend test suite to monitor performance and report regressions...
# Use just 100 to get 'decent' speed on slow boxes

#aux prepare_devs $LVM_TEST_PVS 8
