4) It strongly depends on your network equipment and the PS2 as well. My SCPH-10000 had a SCPH-10190, and it refused to communicate properly with my Lenovo Z460 laptop. When connected, it would only operate in 10Mbit Half-Duplex mode (10Mbit/2/8=0.6MB/s maximum... so it's not surprising if I got only about 100KB/s under those conditions).

The faster the PS2 can transmit, the faster it'll receive data too (It'll be able to send ACKs faster, which the SMB server will then know that it can send more data). The SMAP hardware has its own FIFO buffers too, so it doesn't matter if the IOP is slow or not because the data won't get lost if the network stack is set up right (Flow control of TCP will take care of that).
Again, it does depend on your network (especially if stuff works better in half-duplex there). For some strange reason, I got worse performance when I fixed the speed and duplex settings at 100Mbit full-duplex on my SCPH-39006 and its SCPH-10281 network adaptor (100Mbit half-duplex was fine). However, on auto-negotiation, it was fine (100Mbit full-duplex was selected). :bang:
I think that everybody here will agree that you should simplify your network as much as possible, and to experiment with the settings. I got a slight loss in throughput (~200KB/s on HDLGameInstaller) when my console is connected through a switch which is connected through the main router here. That didn't happen when my console is connected straight to my router.
Also, don't expect too much from OPL when the game uses the streaming functions. Its streaming support code needs to be improved on, and it's probably suffering from a lot of overhead at this point in time (Some of my games have stuttering videos, even though I'm using a HDD).
