1432.0. "X-protocol over 2MB line ?" by IJSAPL::BROUWERS () Wed Sep 13 1989 10:22

    hi,
    
    Can somebody share his experiences with me ?
    I have a question about the speed of the x-protocol over a 2mb line.
    Is it reasonable to run a decwindows application ( case tool from
    oracle, case-designer) over this line ?

    We use DECwindows applications over TransLAN bridge (one 2Mb line) and
    the maximum load is about 2-3 VAXstations using mostly OOTB
    applications (and maybe some DECwrite too) together with about 15-20
    terminal users (ALL-IN-1). We have no problems with this configuration.
    
    Of course You should remind Your customer that this is 'not supported'
    because our configuration guide lines state that minimum line speed
    should be 10Mb/s.

1432.2Mbyte or Mbit? Mb can mean either, these days..HYDRA::COARNobody move or I'll shoot my foot!Wed Sep 13 1989 13:081
1432.3There are international standards for these...ERIS::CALLASThe Torturer's ApprenticeWed Sep 13 1989 13:176
    Uh huh, but what you're *supposed* to do is use "b" for bit and "B" for
    byte. So Mb is megabit, MB is megabyte. Also, for what it's worth, mB
    would be millibyte, a rather absurd quantity.

1432.4Absurd, yes, but not as bad as mb - millibit - or �b ;-)HYDRA::COARNobody move or I'll shoot my foot!Wed Sep 13 1989 16:561
1432.5Mb for megabitIJSAPL::BROUWERSThu Sep 14 1989 07:175
    sorry guys, my notation is not correct, but when i talk about
    communication it mean Mb (megabit)
    Can you share some inportant information with me now ?
    

1432.6MARVIN::WARWICKWell, that'll never workThu Sep 14 1989 18:199
    
    Well, I guess I could repeat my previously written reply again here.
    
    I ran for a while with my workstation connected to the network via a
    64kbps synchronous DDCMP link. Performance of DECwindows applications
    was acceptable, but it was appreciably slower than over ethernet.

1432.72400 baud anyone?DECWIN::FISHERBurns Fisher 381-1466, ZKO3-4/W23Tue Sep 19 1989 18:487
    I've tried it on 2400 baud.  Gaak!  Application startup takes forever.
    Once they start up, it is sort of amusing.  A novelty that you
    could probably use to demonstrate how (flexible, wonderful, ...)
    the system is, but you could not really use it for long.
