Hi Adam,
In fact, the 0.9.10 is very slow, but I did a rewrite of httpd-jpg code and
I believe that this feature will be released with 0.9.11 version.
Try get latest CVS code and you'll see that is really very fast. FlightGear
now is capable to stream the images almost so fast as simulator screen.

Hmm? I have used jpg-httpd to try to capture video and have been
surprised at how slow the performance is. I always assumed that it
was just a limit in the FG implementation, but now that I see the
above it makes me wonder why I am running so slowly. I can probably
get something like a frame every 2 seconds. I have tried using
firefox and curl to grab images and they are slow to download.
Any ideas why I might be having that kind of performance when others
are seeing fast performance?
I am running with FG 9.10 ("release" version not CVS) on a MacBookPro
(2.16 GHz Intel Core Duo) and FG itself gives a good frame rate.
