Can you suggest a benchmark that would demonstrate this. KCL
function calls to functions in the same file were C functon
calls. In AKCL, they're (usully? always?) slightly more indirect
but can be made to pass args on the C stack. So I don't see
why they should be tremendously slow. Does this "nearly an order
of magnitude" mean nearly twice as slow or nearly ten times as
