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 Smilie
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?.

NAME
aseqnet - ALSA sequencer connectors over network SYNOPSIS
aseqnet [remotehost] DESCRIPTION
aseqnet is an ALSA sequencer client which sends and receives event packets over network. Suppose two hosts connected by network, hostA as a server and hostB as a client. The ALSA sequencer system must be running on both hosts. For creating the server port, run the following on hostA: hostA% aseqnet sequencer opened: 128:0 Then a user client 128 with port 0 was opened on hostA. (The client number may vary.) For creating the (network-)client port, run aseqnet with the hostname of the server: hostB% aseqnet hostA sequencer opened: 132:0 Now all events sent to hostA:128:0 are transferred to hostB:132:0, and vice versa. The ports created by aseqnet can be connected arbitrary to other sequencer ports via aconnect(1). For example, to connect hostB:132:0 to a MIDI output device 65:0: hostB% aconnect 132:0 65:0 Then events to hostA:128:0 will be delivered to hostB:65:0. The following command plays MIDI on hostB. hostA% pmidi -p 128:0 foo.mid The multiple clients may exist simultaneously. If hostC is connected as a client to hostA, events from from hostA are sent to all con- nected network clients, i.e. hostB and hostC. However, only one connection is allowed from a client to a server. To disconnect network, stop all clients before server by ctrl-C or sending signal to them. The server will automatically quit. OPTIONS
-p port Specify the TCP port number or TCP service name. -s addr Subscribe to the given address for read automatically. -d addr Subscribe to the given address for write automatically. -v Verbose mode. SEE ALSO
