- The HistoryRequestBenchmark will now perform a daily and minute history
request at end of day.
- C# performance is at ~15k data points per second
- Python performance is at ~11k data points per second
We didn't experience the expected performance improvements. Locally under
unit test there was aboout an order of magnitude throughput increase, but
when run against the history benchmark, this new approach was 60% slower.
We're reverting this for now to perform further analysis and better
understand the performance profiling of the python history stack.
