Compared to what? If you mean engines like Presto, I would say they have different use cases, plus Spark SQL puts them roughly in the same ballpark. Genuinely curious though, as a Spark user that is always interested in alternatives.

kdb+/q performance smokes Spark. Actually. most native code on a single machine smokes an entire Spark cluster.
