Typically, I would just run the benchmark separately for each case,
and then you'd do

# Case 1
python -m perf timeit -s 'setup; code; here' 'code; to; be; timed; here'
[Results 1]
# Case 2
python -m perf timeit -s 'setup; code; here' 'code; to; be; timed; here'
[Results 2]

The other advantage of doing it this way is that you can post your
benchmark command lines, which will allow people to see what you're
timing, and if there *are* any problems (such as a method lookup that
skews the results) people can point them out.
