3207.0. "DECmcc and Client Server (X11) at 64kb/s" by PADIS::PERIE () Thu Jun 18 1992 11:06

    I need to have an idea on the performances given by this configuration:
    
    DECmcc used in a Client-Server configuration on 64kb/s links.
    
    Thank you .
                                             Isabelle.

	Isabelle, I will offer some info, but it may not be appropriate to your case. I have run MCC IMPM across a 128kb DDCMP link from Philadelphia to the UK (near London). This link is used for all sorts of traffic, mail, file transfers, TCP/IP portals and AppleTalk tunnels. The utilization peaks at about 80%. I have (through very brief usage) had good performance up to when the link is running at about 40% util. Once it gets up towards 70% (rule of thumb for saturation of a synch line is 70%), there is very perceptible delays (upwards or 5 seconds at the heaviest saturation point). If your link is running via translans, you may get better throughput. My term "good performance" means that when I clicked a button or called up a menu, the response was, to the eye, instantaneous. Regards
