No, I was not aware of it.  And I studied threads, not coroutines.  The
idea was to have a very similar code, only change the "yield" and
"create" primitives to use several libraries.  Using libcoro would
probably have required to make extensive changes to the small server I
benchmarked.  It would have made more sense to add libev to the bench,
for instance (but then again, I did not know it by that time).

You can find the results here:

(Disclaimer: if I had to redo this study, I would probably do it
differently.  But I moved to something else and do not have time anymore
to spend on this.)
