Apparently yes (look up 'sfio' in the INSTALL file in bleadperl) :
With the PerlIO abstraction layer, there is another possibility for
the underlying IO calls, AT&T's "sfio". This has superior performance
to stdio.h in many cases [...]
If you have already selected -Duseperlio, and if Configure detects
that you have sfio, then sfio will be the default suggested by
Configure.

I don't know. No sfio here, and I'm not aware of smoke-testers that use
it.
