Greg,
the poor performance is mainly due to our network technology:
we use a 9600bps GSM radio modem, that means low speed and
**high**latency**. Our application has a lot of bitmaps and
it is too slow to be useful.
To be honest, this is a problem of our application. We tested
the nano-X demos over GSM, they are slow but at least usable.
The VNC server patch Gianci sent you is based on the framebuffer
and is the most current.
To improve speed on slow links, we are working on a new version,
the idea is to reduce resolution and colors. The crane operator
will continue working at full resolution and color (800x600x24),
and the remote diagnostic screen will have a fast interface with
lower resolution and less colors. This is very application specific
and I don't know if there is anybody interested out there.

: We did something like that on our mobile harbour cranes, but it was really
: slow due to network latency. Each function Gr*() requires a loopback
between
: the application and the server, you can imagine the result.
Actually, the design is such that most functions return void, and as
such are batched and sent to the server without requiring a round-trip.
Of course, any Gr*() function with a return value requires loopback.
I'd like to hear a bit more about the slowness issue.
:
: We ported VNC server to nano-X using libVNCServer by Johannes E.
Schindelin.
: I don't know if Greg has received the patch - if did not, I can send it
now.
I have the patch from Gianci dated June 20th, based on libVNCServer v0.2.
Is this the most current?
Regards,
Greg

: Hi,
:
: I have had nano-x built on a PPC platform(server linked in) for a
settopbox
: kind of application.
:
: now i'd like to seperate server and client such that nano-x server running
: on
: the ppc platform, while client running on a x86 based linux box or win32
: platform....the apparent idea is to seperate the gui running on the linux
: and/or win32 system with the firmware in flash memory on ppc platform, gui
: change/upgrade would then be independent on the ppc box.....
:
: anybody has done such kind of things, and any idea, tips or caveat to
: advise??? Thanx
