    It does reduce the use of bandwith

    I see absolutely no advantage with that. I have an abundance of bandwidth. Almost all connections is done within a second.

    You said almost, but just last week I had a 3 hour binkd connection, that could
    have been done 70x faster, with better compression! And that connection interfered with other (fido) processes. Compression is still very usefull in todays internet!

    Well, I try to stay away from binkd transportation of stuff in the multi-gigabyte class. 8-)

    Yeah, it made a just in time, same as last week pointlist segment to be delivered five minutes late. Big deal.

    It was a one time incident that is unlikely to ever be repeated in that way. One does not base policy on a one time, never to be repeated incident.


    Cheers, Michiel

    Bandwith is still a limited resource and more expensive than computer cycles. Afaik data transfer is still metered by the byte on the peering level. So you might not pay for it directly. But it probably makes a difference how much data
    is transfered by all their customers combined, what internet providers will have to charge as monthly subscription rate...

    Bye, Wilfred.

    Big deal since it was the same as last week's...

    True, but the traffic generated by fidonet is neglegible compared to all the other traffic.

    Also I wonder if binkd compression would have made any difference in the incident you metioned. I send a large compressed file, but made an unlucky choice for the compressor. Could the binkd compression have compensated for that? Maybe, but it would not have, since it is configured to not try to compress already compressed files.

    As I said before, this was just a one time incident that will not be repeated. Next time I send such a file, I will use a better compressor. One does not base
    a policy on a one time incident that will in all likehood never repeat.


    Cheers, Michiel

    That's not important, it could have mattered!

    That's like saying your not going to vote because your single vote wouldn't change the outcome of an election. That's "true" also...

    It might have made a difference if you didn't compress it all, but not nearly as much as the 70x that 7zip improved on it. But your current mingw version of binkd only supports zip compression not bzip2 compression, so than it wouldn't have mattered...

    Wilfred.
