 To obtain the maximum performance out of the system, you can tune the `threadcount` parameter in the script. As a reference, for a `c5.4xlarge` instance with 16 cores and 32GB RAM, you use a threadcount of 32 for the loading phase and 256 for the execution phase.

 The `run_jdbc.sh` script creates two result files per workload: one for the loading, and one for the execution phase with the details of throughput and latency.
