> With 1500 mtu what kind of throughput you see when all 4 NICs are used? We're only using two NIC's so far. We see 90-95 MBytes/sec on a single link with the current setup. Without the squeue settings it was 50-60 MBytes/sec per link. It doesn't take much load to make a T2000 thread 100% busy. >Marion said: >> We have not changed the settings for ip:tcp_squeue_wput nor ip:ip_squeue_wait >> here.

Here's what we're doing: http://www.solarisinternals.com/wiki/index.php/Networks#Additional_tunable_for_ systems_with_1.0GHz_CPU This limits interrupt handling to one thread per core. Just doing this without any of the IP tuning made a difference on our T2000's (44 MBytes/sec before, 50-60 after); As you said, it likely would not matter on your system, which has much faster CPU cores than the T2000.
