Getting undesired tpc-c benchmark result for tidb cluster

[Abhayasai]

I'm new to tidb and trying to benchmark my tidb cluster using tpc-c. I'm running a tidb cluster with 3 tidb,3 tikv and 3 pd services running on the 3 azure VMs. After running the benchmark commands for 20 warehouses, i got the invalid result(tpmC: 7577.6, tpmTotal: 16770.1, efficiency: 2946.2%).

Here is the result printed:

the high efficiency since the number of warehouse is too small, please increase the number of warehouse to 1000 and retry.

Is there any way to do performance testing with 100 warehouses? because i need to test that small data set only for better comparision.
