Hello All,
We are experiencing a problem doing FTP to or from a mainframe S390 running
MVS where as it is extremely slow. It only seems to be a problem on our
HP9000 systems (N4000, RP7400, K370) running HP-UX 11.0. We were getting
around 35 meg/s throughput. We tried FTPing the same file from an IBM
RS/6000 running AIX 4.3.3 and were getting over 500 meg/s. On the HP9000
and the switch we set the speed of the NIC card from 100 Meg Full Duplex to
10 Meg Half duplex and the speed of the transfer went up to 150+ meg/s. I
looked at the ndd command and tried changing a couple of the buffer settings
but it did not help. I am not quite sure why AIX systems transfers the file
at a normal rate but the HP system does not. I was wondering if anyone else
had experienced this and if so was there a way to fix it?
Thanks,
Jim Naylor
