Yeah I suppose that’s the real question - what is the size of the target market of Fil-C? I believe it’s a small % because many C applications are performance sensitive. You say performance is only one consideration among many so the % of C applications that would benefit from your compiler are much higher.

You’re the guy actually building this, so you would have talked to potential customers more than me. You’re more likely to be correct, but I would be interested to know what these applications are.

Also, do you hope people pick Fil-C for a new code base over other performant GC languages like Go, Java and C#? These have less than a 2x overhead for CPU bound tasks.
