Notes

• The framework only reports the client-perceived latency at the moment.
• The benchmarks are run sequentially, concurrency support is in the roadmap but is not implemented yet.
• Note timestamp bound support is work in progress.
• Framework can warm-up the sessions before starting to benchmark. This improvement is in the roadmap.
