The slowness of fromHex is not because it throws an exception. The real reason is the fact the point decompression is slow. To decompress a point, you need to exponentiate its y coordinate by approx curve order ~(y^(2^252)). As you can imagine this operation is extremely slow.
If you want a speedup, you can use decompressed 65-byte points.

Thanks, that makes sense.
