Right. We had two identical FreeBSD 2.2.7 clients (PentiumII) and one SunOS 4.1.x Server. No nfsv2/nfsv3 or tcp/upd options were specified in the AMD maps at all. . Originally, both clients were operating without any problems. . We upgraded the server to Solaris 2.6. No problems. . We upgraded one client to FreeBSD 3.1. Out of a sudden, NFS got rather slow and regularily we had NFS access hang for some seconds to a couple of minutes or even more. No problems with the FreeBSD 2.2.7 machine. . I added "nfsv2" to the AMD maps. Suddenly the FreeBSD 3.1 machine was as fast as it was when running 2.2.7. The behavior of the FreeBSD 2.2.7 machine remained as fast as it was. (Please note that our current Ethernet is rather bad and overloaded from a hardware point of view.) > If the list truly feels that v2/UDP should be the default rather than > v3/UDP, I'll glady change it for -STABLE (but not -CURRENT).
