[arachne] Re: Slow scrolling of large screens

Arachne at FreeLists---The Arachne Fan Club!

Here is another example of the slow scrolling/flickering effect that I
have described before:

Go to

http://www.drdosprojects.de/forum/drp_forum/

and hit F6 to display the page source, then start scrolling the screen
to the right with the <cursor-right> key.

On my machine, after scrolling about 10% of the width of the virtual
screen, scrolling suddenly becomes much slower, and the flickering
effect kicks in. Also, Arachne starts to display "Refreshing screen" in
the text bar at the bottom. This happens even if I scroll the screen
back to the left border again.

To me it seems like this is a problem with Arachne, not with my
hardware. It looks like Arachne would suddenly disable the virtual
screen feature until I reload the screen again.

On my Pentium4, it takes 48 seconds to scroll the screen all the way to
the right. The actual speed varies with the amount of text or graphics
that is present on screen. Maybe fast hardware helps in reducing this
time, but then I wonder how long an older machine might take if even a
Pentium4 has trouble. ;-)

IMHO, any "feature" of Arachne that makes a P4 look like an XT should be
regarded as something that needs fixing ASAP.

Almost forgot to mention it; this is of course in Arachne 1.90JG, the
latest and greatest. ;-)
