Modification of tcp buffers on HMC adapters for improved performance to different AIX versions

The customer is requesting a supported procedure on how to modify the TCP buffers on the HMC in order to tweak the connection, because of the following scenario:

From the 6.1 LPAR to HMC scp is running at 350KB/s
From the 5.3 LPAR to HMC scp is running at 11MB/s

received the test results from ftp :
HMC <-----ftp (get)------ LPAR AIX 6.1 (3.8e+02 Kbytes/s)
HMC <-----ftp (get)------ LPAR AIX 5.3 (1.1e+04 Kbytes/s)

The customer had slowness when doing a VIOS restore from an image that
was placed on NFS share on AIX 6.1 6GB backup file took nearly 4 hours to pull.
He used the "installios" command, to restore a VIOS from a nim_resources.tar file located on remote NFS share on AIX 6.1

    As per discussion with Karyn, the jumboframe option should address this requirement and hence marking it as delivered.

    Thanks.

    .The HMC chhmc CLI supports a --jumboframe {on | off} parameter. If you configure this on HMC, partitions, and any switch between the two, would that solve your problem?
