ok, I don't see any errors or overflows or underruns on any of your adapters.That is a good thing. You can transfer large package sizes to everywhere else without loosing packages - which is a good thing too.
It would have been nice to know which adapters make up which link aggregation, but I forgot to ask for it
A few things I see in your network tunables, that I would probably change if this would be my systems to improve the general network flow, (i.e. sack, tcp_nodelayack, and buffer sizes) but for that it would help to know exactly which adapters make up which link aggregation. So if you could show me the lsattr -El entx outputs for your link aggregations and the underlying physical adapters that would help to make sure you dont use different speeds and depending on the adapters, the device attributes are set correctly. It might help as well to set certain settings on the adapters themselves in addition to the general system settings, like rfc1323 and buffers. And I can see that you have relatively little free memory. This may or may not be a problem so if you can give me the outputs of vmstat -v and vmstat -s, that would help me tell you the answer to this. You may as well want to populate netsvc.conf as it helps with order of name resolution and might generally improve network speed when the system does not have to guess how to find another host.
To get rid of the pkcs error on top of the lsdev -Cc adapter output, you probably need to install the security.pkcs11 fileset. And finally, can you please run lppchk -vm3 and post the output as well?.
