We’re currently enabling automated testing of the version of Hafah that uses PostgREST instead of a python-based web server. Our benchmarking so far continues to show a substantial benefit from using PostgREST, with one of the latest tests showing a 2x improvement in response time (100ms for a 500kb response versus 200ms in the python-based server) for a get_ops_in_block call (which was previously the biggest bottleneck during our Hafah benchmark test). I believe this work will be completed by tomorrow.
