Not yet - there is a bench vs clickhouse that has been done by one of their contributor though see below in the comments.

Hi! The performance gap between questDB on both ingestion and queries versus timescale or influx is very significant (orders of magnitude faster). questDB is being used in production for critical use cases at large companies and is definiti
