# Test to exercise larger number of PVs in a VG
# Related to https://bugzilla.redhat.com/show_bug.cgi?id=736027
# 
# Original measured times of the whole test case before 
# and with the acceleration patch from my bare metal hw
# (Lenovo T61, 2.2GHz, 4G RAM, rawhide 2015-03-06 with ndebug kernel):
#
# export LVM_TEST_PVS=300
#
# make check_local   ~52sec  (U:29s, S:13s)
# make check_lvmetad ~20sec  (U: 4s, S: 5s)
#
# With patch from 2015-03-06:
#
# make check_local   ~30sec  (U:10s, S:12s)
# make check_lvmetad ~20sec  (U: 4s, S: 5s)
#

# TODO: extend test suite to monitor performance and report regressions...

# Use just 100 to get 'decent' speed on slow boxes
LVM_TEST_PVS=${LVM_TEST_PVS:-100}

#aux prepare_devs $LVM_TEST_PVS 8
#vgcreate $vg $(< DEVICES)

# prepare_vg is now directly using steps above
aux prepare_vg $LVM_TEST_PVS

# Check we have decent speed with typical commands

# TODO Turn this into another test case:

#	vgcreate ${vg}$i "$DM_DEV_DIR/mapper/${PREFIX}pv$i"
