Your wallet will show you the chain ID and endpoint before adding anything.
Checked, not benchmarked. One request from one machine, twice an hour. Enough to tell you whether an endpoint answers; not a latency measurement, and not comparable with the benchmarks elsewhere on this site. Public endpoints also disappear without notice.
