[ping latencies fluctuates with conexant adsl driver]
Does anyone know what could be causing this.
You will have a hard time figuring it and many people (me included)
will keep a good distance with an issue which includes > 400 ko of
unknown gcc 3 compiled binary code (even if the md5 of the binary
things are the same for the 2.4 and the 2.6 driver).
They will be the same as connexent haven't touched the drivers for
years, Patrick ported them to 2.6 and a diff doesn't show any difference
involving HZ that I can see.
I suppose there could be something in the binary that says if HZ <1000
use it if not use 100 but I could test that - remember running 500 on
2.4 "fixed" things.
I still don't know how the driver would "know" the difference between
local and forwarded traffic?
That being said, it seems that the 2.6 version of the driver uses
workqueues where 2.4 driver used native kernel threads. You can
experiment with the priorities there.
I'll have to google around that one - but I still secretly hope it's not
the driver anyway.
Can anyone think of any kernel code that changed to use HZ/10 when HZ
was increases to 1000?
Andy.
