I’ve never directly played with Ada but my understanding is that it was very much both.
Ada includes a number of critical abstractions that require either dynamic runtime code (slow runtime) or the proverbial sufficiently smart compiler (slow compile-time).
These were for good reasons, like safety and the need to define concurrent systems within the language. But they were too heavyweight for the commodity hardware of the era.
Nowadays, languages like Go, C++, Java, Rust, … have no trouble with similar abstractions because optimizers have gotten really good (particularly with inlining) and the hardware has cycles to spare.
