Quoting Ian McDonald:

^--- u mean `private' ?

If it helps to let off steam ... I am not bearing any grudges. It is good to
vent anger (as Metallica would have us believe). The converse is unhealthy
(as Karl A. Menninger `Man against himself' makes clear).
With regards to offline discussions - yes, please, I would indeed much rather
have them out in the open.

| Against earlier code a couple of months ago with a couple of my
| patches I was achieving around 90 Mbits/sec on iperf which matched TCP
| performance and it was stable. It responded gracefully to loss also.
I have two boxes with Gbit cards here and saw speeds up to 750..820 Mbit.
It seems that the computation overhead allows it to reach up to 80..90% of the
link bandwidth (with coarse-granularity problems still unresolved).
| I have not tested lately and tried to replicate but I know that the
| state of tree before current patches couldn't do that any more... As
| time permits I will redo the work.
Do you remember when the `bidirectional' patch was reverted? - after that the
CCID3 sender slowed down again to 75..80 Mbits/sec on a 100Mbit link.
This comes from the processing overhead, and was the original motivation for
this patch.
That incidentally was the second `moronic' patch I had submitted (as it limited
connections to being one-directional). Without Andre's help it would probably
still
be in. This really is the point I was trying to make in the email - I think we
need to
focus more on the code. Here are two cases where the missing review/input came
from outside.
I am not claiming to be any special. My hacking skills are rather moderate
(i.e. you
have been warned about them patches :)
Thanks.
