Re: GSW and performance

Hi,

In the case of LOSS option in Feedback packet,  if there is a large number
of
sequential packet drops, then the gsw size should be increased accordingly
to minimize
the losses at decompressor.

But,
If we increase the size to a large value (example - 50 or more), then it
will take
lot of time(processing cycles/cpu cycles) to operate(Encoding) on the gsw as
it
has to consider all the values inside the window .

So, what could be the optimal gsw size such that it does not affect the
performance(processing cycles/cpu cycles) and also the packet drops.

Thx in advans,
Karthik Balaguru
