Just a thought.
Do you have to change the MTU size at all? I think it defaults on linux to
1500.
Just a thought. Does the MTU size even play into the hipersockets at all?

Depressing isn't it? I've never been able to get much (or any) better than
what you have. I don't know why either. The only thing that's kept me
from
goin' round the twist was a little program called netpipe. A completely
synthetic benchmark program, but it at least showed me that the
hipersockets
CAN acheive high throughput. I just don't know how to make it happen for
FTP between Linux and z/OS.
Here's the best rate I got from a run I just did:
7: 39936 bytes 1010 times --> 1274.84 Mbps in 0.000239 sec, avg
utime=0.000000 avg stime=0.000226, min utime=0.000000 stime=0.000198, utime
var=0.000000 stime var=0.000000
If you find out, I sure would appreciate it if you'd clue me in on the
secret.
