Hi Mike,
Excuse my stupidity, but I don't suppose you could put this as a table
with something like:
Time %Dropped
Original
Ecore Cur
Ecore + MikeM
I don't fully understand your data, but your argument seems to be that
the final patch from mike continues to:
- Improves Performance
- Reduces % of connections dropped
So I'm not sure what the issue with accepting a small patch to change 1
week old. Except the for the old e-devel list of rejecting small
patches, but letting the big ones sail straight through.
Regards,
nash
