For such a small team developing SBCL, it has been hugely stable, consistent, and advancing for years. SBCL has many ways it could improve, but it definitely exceeds most bars of quality for serious—even commercial—projects.

I haven&#x27;t looked in a while, so I&#x27;m wondering what SBCL&#x27;s GC latency profile is like nowadays. IIRC, it used to be a non-incremental STW conservative GC, which is a bit unfortunate.
