I am running into what appears to be some slow connections across

transfer across these connections is reportedly very slow. Most
transfers across these connections are SQL queries and responses at this
point, with some file transfers. In many cases these queries are quite
large, or are many many small ones.
Any possible suggestions as to what I can check on this, or
settings/options I should look at?
I had a similar problem with Samba & NFS a few months ago. The Samba
problem was cured with the "interfaces" option in smb.conf. I never did
get the NFS problem resolved.
Most NFS over CIPE problems can be solved by using the NFS mount
options "wsize=1024,rsize=1024". This makes NFS use read and write
sizes small enough to fit into a single CIPE packet. By default it
uses read/write sizes large enough to require fragmented NFS packets
that sprawl across multiple CIPE packets.
