Could you please provide the same information (except the second sysctl one)
from the target machine as well. You don't have to show the difference
http://rhb.uugrn.org/FreeBSD/bugs/5.x/1000-to-100/check_target.txt
Ok, this give some very stange information:
On the taget machine (4.10) we see a huge amount of OO packets arriving:
92920 out-of-order packets (134546620 bytes)
but we don't see nearly that many on retransmits on the source machine (5.3):
281 data packets (405792 bytes) retransmitted
However the data set on the target machine seem to be skewed. There is a
lot of other TCP traffic on there as well. So this probably doesn't really
relate directly to the test you did.
between before and after but try to make sure that not much other traffic
was going than the test.
Just my ssh-Session. But I can't guarantee for each packet passing the
router (= the target-machine). There's no "production"-traffic on that
subnet, just my testboxes.
Hmmm... Without getting the TCP statictics back to zero it's hard to correlate
any data.
Would you mind trying a 5.3 to 5.3 transfer but the target 5.3 box forced to
only 100Mbit full-duplex? Same statistics again.
