it is wrong to assume that unsigned long is 32 bit long. I would doubt that it is correct to give every set bit
the same weight when
they have the the distance of sizeof(unsigned long)*8. And I cannot find a
good reason why an "old" unsigned long should get the same weights as the
"newest" unsigned long - at least not when the actual weights should be
reduced for "older" bits in a single unsigned long and the overall weights
should be monotonic decreasing with the age.
I am looking at how i can deal with
this part.
And using WORD_BIT_SIZE for j
is
like assuming that we only have a single unsigned long in seq_bits... which
is
not true for many architectures.
During the debugging i realized that this can
handle more than 1
unsigned long in seq_bits, i just need to prioritize the newer ones to
the old.
And the code is overly complicated without any good
reason.
I also thought so but so that it was the simplest i could come with,
still drawing up some other ways hopefully i will improve it with
time.
Kind regards,
Sven
I have been doing some tests using iperf/jperf to simulate traffic
between host. The results show lot of packet loss (though
inconsistent) and i am not sure if this could be the results of
overheads in the network. Is there anyway i could debug the amounts of
overheads on the network? What testing methods do you and your team
use?
