Hi,
The default listen backlog in sunrpc/svc_tcp.c and sunrpc/svc_unix.c
is too small for modern servers. Here is a fix (which is similar to
the solution from TI-RPC and all *BSD ports do) to increase the
performance. We use it already since some time for SuSE Linux.

* sunrpc/svc_tcp.c (svctcp_create): Call listen with SOMAXCONN
as backlog.
* sunrpc/svc_unix.c (svcunix_create): Likewise.
