Performance impact of linking libwrap

HI!

I'm currently trying to upgrade an OpenLDAP package for a openSUSE distribution.

The original package links slapd with libwrap which made sense in former times on systems without local host firewall mechanisms. If libwrap does not have a major performance impact I'd keep it that way just for sake of backward compability.

But AFAICT if slapd is linked with libwrap the TCP wrapper is always asked whether a connection is allowed or not. One cannot disable it by slapd configuration.

So the question is: How big is the performance impact?

Ciao, Michael.
