I suspect that TimescaleDB benchmark code still create wrong index for --in-table-partition-tag=true
I described it before inside https://github.com/timescale/tsbs/issues/182

I see. Thanks for the information! Were you able to fix it and speed the query up? e.g., manually create the correct index (tag_id, time).
We generate and load IOT data into Timescale following exactly the readme.md (https://github.com/timescale/tsbs). However, we observe the query performance is very different from what reported in https://www.timescale.com/blog/how-to-benchmark-iot-time-series-workloads-in-a-production-environment/
For instance, the last-loc query takes around 14 minutes to finish on our server (with shared_buffer=128G, work_mem=4G, and maximum_worker_number=64). While the running time is around 1s in the blog. May we ask what else we need to tune in order to get that performance? Thanks!
FYI, we tried different physical layout configurations during data loading:
