This comparison is vs. InfluxDB. This thread is about a new project called InfluxDB IOx. It's under development and we're not producing builds, so any kind of operational comparison would be very premature.
Its architecture is dramatically different than InfluxDB. You can do a comparison of the design goals. Read the post this thread refers to. I think you'll find it has very different goals than Postgres, an OLTP database, and Timescale, which is built on top of it.
