I think you make a pretty good case here for adding a new helper method to SSLeay that would offload some of the work of IO::Socket::SSL into XS. Hopefully the maintainers are intrigued by the problem. In the meantime, assuming you have work to get on with, your application should probably just use SSLeay directly :-) Maybe just have it assume that a undef read is an unproductive read for the first N times it happens, then check the error codes if it continues failing?

I'd also like to point out that the flame graph looks like you could save about 10% overhead by calling $socket->sysread(...) instead of sysread($socket, ...) which is why I suggested that earlier. It's unfortunate that perl's global functions add that much overhead when operating on a user object, but a good incentive to move to OO-style syntax on handles.
