Thanks again for the info.  I can say wtih confidence
in my case (two sets of triple head Series 1 and a
single 150) that the packets are being dropped by
the DTU and not the network.

Tell me what to capture and I will provide it.

Again, I have to disagree.  I see it even when neither
the network nor the DTU reports drops packets.

I  would add to that list switching virtual screens,
loggin in, output scrolling in gnome-terminal, scrolling
in firefox, scrolling in evince, scrolling in OpenOffice,
or scrollin in anything plus anything flash.
Also add in another OS via virtualbox and pretty
much anything else reasonable office worker would
do outside of xterm with compression mode and
the response screams that this is slow and you
are better off using a local box.

All of those limitations are ok if we accept that the
DTU is incapable, the network is incapable, the
server is incapable or there is some massive benefit
to tolerating the pain.  At this point I would wager
that a Linux-based X terminal would outperform
SRSS right now, and that's sad, because I got
away from X stations to move to SRSS.

At least tell me there is an obscure debug mode
where SRSS logs, "Switching to compression mode
because XXX detected" so that I can pin down its
rationale.

Thanks again,
Marty
