All:
As you all may know I have been working on getting SCTP
into Current..
I have been, of late, trying to tweak things to get
the BEST performance out of the implementation...
I have moved my testing off between two 7.0 machines.. same
code base on each updated Sep 25.
One is a 2.8Gig Dell SC1600 Xeon.. (hyper threaded CPU).
The other is a P4D (2.8Gig .. slightly faster, true dual
processor machine).
They are connected by two intel EM server cards like so:
+----+ +----+
1 | em1 <---------------------> em0 | 2
| em0 <-----locallan--------> msk0|
| dc0 <-Direct Inet |
+----+ +-----+
em1 has 10.1.2.12 em0 10.1.2.21
em0 has 10.1.1.12 msk0 10.1.1.21
[...]
One other note, I see TCP is only getting 250Meg or so on the
same test (It can run either).. now it used to get close to
the full pipe (Gigbit).. so is there some issue with the new code
that was recently submitted?
I'm not sure but it seems that you've used experimental msk(4) on
CURRENT. ATM msk(4) has Rx performance issue. So if you get very
poor receive performance it would be msk(4) issue.
