In the Data-serving benchmark document, the instruction for setting up the client is kind of vague:

Before running the measurement, you have to fill the server with the dataset. Use the script warmup.sh:

$ ./warmup.sh <server_ip> <record_count> <threads=1>

Users cannot determine the exact input format (whether we should specify the record_count in decimal or hex format, whether we should include threads= in the argument ). It can be improved by adding an example with default parameters specified.
