[Gvsig_english] v1.9 alpha on Ubuntu 8.10

Sun Feb 15 11:05:20 CET 2009

Hi Chris,

I used the term performance is two ways. The first relates to rendering and
you are right about the hardware. I have a line feature with 375,000 lines
that renders in about 6 seconds (with a spatial index) using the Celeron box
running Ubuntu 8.10 and OA 1.1.2. Same file and software on the Pentium dual
renders in about 2 seconds using Ubuntu 8.04 and with win NT using gvSIG 1.1
the line feature also renders in about 2 seconds. I'd suggested this is to
be expected.

However, the second way I used the term performances relates the usability.
Using the Celeron box with Ubuntu 8.10 and OA 1.1.2 is quite slow. By this I
mean when I click a button there is a delay. If I drag a window is takes up
to 3 seconds to redraw. All the basic features I used take more than a
second to complete. This is not the case with the 8.04 version and seems to
be limited to 8.10.

Unfortunately, I cannot put 8.04 on the Celeron box as I can't get it to
work properly with the graphics card and my 22" monitor.

Sorry if my mixed use of the term performance has cause confusion.

Cheers

Colin
