Interesting data point. My test case is like this:
server
bind
listen
while (newsock = accept...)
transfer()
client
connect
transfer
If the server side is the source of the data, i.e, it's transfer is a
write loop, then I get the bad behaviour. If I switch them so the data
flows in the other direction, then it works, I go from about 14K pkt/sec
to 43K pkt/sec.
Can anyone else reproduce this? I can extract the test case from lmbench
so it is standalone but I suspect that any test case will do it. I'll
try with the one that John sent. Yup, s/read/write/ and s/write/read/
in his two files at the appropriate places and I get exactly the same
behaviour.
So is this a bug or intentional?
