HP TCP/IP Services for OpenVMS Alpha Version V5.6
on an AlphaServer DS10L 466 MHz running OpenVMS V8.3
Doing a TCPIP MOUNT blah will give a default read/write size of 8192
according to TCPIP HELP MOUNT /DATA. If I want to increase the size of
the chunks transmitted, I expect that I can issue a TCPIP MOUNT/DATA=X,
where X is some multiple of 512. If I did /DATA=16384, I expect that I
will be transferring 16k chunks.
The server and VMS client are connected on a Gigabit switch, the VMS
client is connecting at 100Mbit/Full (according to LANCP) with a buffer
size of 1500.
Will changing NFS data size provide an improvement in transfer speeds?
The NFS Server is happy for me to vary the data size….
Cheers
