[9fans] Slow Drawterm

[9fans] Slow Drawterm

[Fernan Bolando]

Hi all

It is noted in the 9grid.jp website that drawterm from another country is slow.

Does anybody have any suggestion to improve it?

I noticed that using ssh is much better so I changed my
lib/profile to exec rc when I login using drawterm. It seems better but ssh
is noticably more responsive.

thanks
,Fernan

Implement some form of compression in devssl 
and then make drawterm use it.

I am resending this to 9fans. Russ sorry for the spam

Since I am still exploring plan9 and coding this is beyond my skills.

Anybody have any special configuration to get a usable interface to the 9grids?
Currently I am using drawterm and my profile runs rc only instead of
rio. This is
ok, I can still do a bit of usable work this way. I am just wondering
if there are other
ways poeple are using drawterm over slow connections.

If you run Plan 9 or drawterm to a local machine, then you
can use cpu to connect to the other machines or import
their file systems and run the editor locally.  This way
all the gui is near you and more responsive.

Would this really help that much ?

In my experience, most slowness comes from the
ping pong nature of 9P on high latency connections.

I've found that many high latency connections are
really low bandwidth connections in disguise.
Running drawterm or "ssh -X unix-machine acme"
is very slow from my apartment to MIT, but
ssh -XC unix-machine acme is zippy enough that
I forget it's remote.

those ports and get a benefit automagically without touching drawterm
sources then?
