I am not sure what you want to know / to do.

Each adapter can have its own rspool/spoolsizes, no problem. The
question is what values make sense. For some software, f.e. vsd, there
are recommendations.

If you have performance problems, its probably more wise to look at
tcp-parameters ( no command ).

** High Priority **

Hi friends,
We have SP Switch (check MX type) connected 18 nodes including two S80s.
At present we have diffrent{ spoolsize,rpoolsize) among two S80s in
which one is production having 5mb and other is quality also running
TSM server have 16mb.And rest of the 16 nodes have 4mg size. I am
planning to change (spoolsize,rpoolsize} size parameters from 5mb to
16mb in production to make equal to TSM server which is in quality. My
question is... Do I need to change in all sp nodes to make this work?

OR

the spoolsize and rpoolsize values MUST be the same on all nodes using
the switch.

please advice me .

thanks and regards
/mani
