My experience from test workloads on Cockroach is that single transaction performance is very bad compared to something like Postgres -- with 2.0 I was seeing easily 10x worse performance than Postgres with a three-node test cluster on Google Cloud. My impression is that it's worse for apps that have lots of small CRUD transactions on low numbers of rows, as is typical with web/mobile UIs. Aggregate cluster performance seemed very good, though; i.e., adding a bunch more concurrent transactions did not slow down the other transactions noticeably.
