Since both read and write boundaries are being changed, doesn't netperf need to be run in each direction?

I have two twin systems: PowerMac G4 both with 3com 3c996T connected to a 3com
gigabit switch, same memomry, same disk, same os. I have compiled and installed
the driver with the harcoded best dma configuration on both.

These are the netperf results from one side:

afs02-i:/usr/share/doc/netperf# netperf -H afs01-i
TCP STREAM TEST to afs01-i
Recv   Send    Send
Socket Socket  Message  Elapsed
Size   Size    Size     Time     Throughput
bytes  bytes   bytes    secs.    10^6bits/sec

87380  16384  16384    10.00     671.71


And these are the netperf results from the other side:

afs01-i:~# netperf -H afs02-i
TCP STREAM TEST to afs02-i
Recv   Send    Send
Socket Socket  Message  Elapsed
Size   Size    Size     Time     Throughput

87380  16384  16384    10.00     667.96

And on the local device:

afs01-i:~# netperf -H afs01-i
TCP STREAM TEST to afs01-i
Recv   Send    Send
Socket Socket  Message  Elapsed
Size   Size    Size     Time     Throughput

87380  16384  16384    10.00    1834.33
