783.0. "TERMINAL EMULATION PERFORMANCE" by 16589::WILSON_DO () Tue May 16 1989 00:25

    HELP,
    	I,M IN A COMPETITIVE SITUATION AGAINST HP AND THEY SEEM TO HAVE
    PLANTED A PERFORMANCE ISSUE IN MY CUSTOMERS MIND.  THE CUSTOMERS
    HAS REQUESTED ME TO PROVIDE DATA ON HOW FAST A VAXSTATION 3100 CAN
    WRITE TO THE SCREEN UNDER DECWINDOWS.  THE PARTICULAR REQUEST IS
    WRITING ASCII CHARACTERS TO THE SCREEN USING THE TERMINAL EMULATOR,
    HOWEVER ANYTHING WOULD BE USEFUL.  MONOCHROME OR COLOR, GRAPHICS
    OR TEXT, IS ANYONE AWARE OF DATA THAT WOULD BE USEFUL?
    						THANX IN ADVANCE,
    							DOUG WILSON

783.1DECterm is a a VW layered on a PorscheKOBAL::VANNOYJake VanNoyTue May 16 1989 09:463
    If you plan to win, don't use our terminal emulator.  Compare raw X
    text performance at the Xlib level.

Re: .1

Ouch, good one, Jake.  We just haven't had the time to improve performance
*and* reliability *and* functionality, and DECterm deserves (and gets) flames
in all three departments, but hopefully things will improve over time.

    Hell, sell 'em UIS, my figures show >20,000 characters-per-second
    on a monochrome VS3100 running VWS V4.0 and VMS V5.0.
    
    The VMS performance group should have all the DECterm numbers (since
    I got them from them to make comparison charts - don't ask me for them),
    try someone like John Buford (think that's the name...).

You may also want to ask about DECterm performance in the Workstation
Conference at SHPLOG::WS_COMPETITIVE_FORUM.

	Does the customer really need great DECterm performance, or is HP
just trying to distract them?

783.5Beat HP on this one.32881::WATSONWed May 17 1989 12:5215
    I competed with HP on a similar issue and won.  I used a version
    of Steve Klein's Vlist widget to show how fast we could scroll text
    (write text) to a screen.
    
    We didn't measure cps, just seeing Vlist move as fast as it does
    and consume as little system resources as it does was enough to
    win.
    
    See note 50 (?) in DW_EXAMPLES.
    
    Send me mail if you need more info.

783.6DECterm & Reverse LAT? w/ TransLANGLDOA::MORRISONDaveFri Jun 02 1989 23:4411
    I have a related HP need - this one to connect to an HP3000 MPE
    from a VS 3100 DECterm window connecting to a reverse LAT session
    and also to open a 327x session through a window also. Both of these
    will need to run accross TransLAN to the remote 370 and HP systems.
    Is this feasable much less practical? What the customer really wants
    is for the HP window to show a full screen. If this is not possible
    with reverse LAT perhaps ther is a HP terminal emulator out there
    which can run layered on VMS. ANY help in this will be most
    appreciated. My normal area of involvement is in networks and not
    in workstations so pardon any ignorance. Thanks.
