That "Think Time" that you are referring to is supposed to emulate users running transactions on the database. So its not the database waiting its the driver waiting. While I do understand the reason for putting that in, you know very well that violating that limit doesn't artificially give CockroachDB or MemSQL an advantage when you are talking about 100,000 warehouses and a random distribution off transactions.

If CockroachDB is concerned about THINK TIME enough to ask for the numbers to be removed, this would be a great opportunity for them to remove that limit and see exactly how much they could push the benchmark.
