ATC speed instructions, wind and altimeter indications

ATC never gives me speed instructions in simulation; how common are
they in real life? I presume they know enough about aircraft types to
know how fast or slow they can go?

I fly a Mooney so speed restrictions are not uncommon when approaching
busy GA fields.
Strangely about a month ago I was coming into SMO VFR and about the
time I crossed the fence tower said "93V, you're too fast". I have no
idea what that was suppose to mean but I continued to land since he
didn't say otherwise. I asked my wife afterwards if I heard it
correctly and she said I did. Since there is only about 10 seconds
between crossing the fence and touch down there wasn't time to ask
questions. Anyway, that's my "that was very odd" ATC story. Maybe he
didn't think I could stop in time. I think I was doing 170 kts on
approach ground speed but was only doing about 100 over the fence. Not
too uncommon speeds for very busy airports.
