# Extra DaisyNFS/GoJournal commit combinations can be tried by passing extra

#
# > ./bench.sh 1 abc123,xyz456 def123,master
#
# Will, in addition to the standard battery of tests, also run DaisyNFS with
# commit abc123 using GoJournal with commit xyz456 and
# DaisyNFS with commit def123 and go-journal master.

# run various performance benchmarks
