Here's a question from one of my cohorts, since this is our first try at this,
I thought I would see if I could get any input from anyone else doing this.
We have been testing jumbo frames(8990) using TSM on an AIX client. The base
line test with MTU of 1500 moved 22G in 44 minutes. Changing the MTU to 8990
and the TCP receive and send buffer sizes on both the mainframe and AIX client
to 256K, the same 22G of data takes 1 hour and 40 minutes.
Also the largest input packet size is 8192, not 8940. Are their any tcp
parameters to se on the client that would help with the jumbo frame transfer
time?
