[GRASS-user] Hardware config/limits

[nunosousa84]

Hi,

I've noticed that i have serious problems dealing with large raster maps and
some GRASS commands in Grass plugin, like r.surf.contour, shaded relief,
some raster calcs, etc... Im using 1 by 1 resolution, maybe it is a bit
exagerated, but even at 5 by 5 the calculation process is very slow. Im
using a Intel Core 2 Duo E8400 and 4Gb 8500mhz DDR2 Memory. Im about to do
an upgrade, should i opt for 8Gb memory, or i better opt for a good CPU
(maybe quad core)? Whats your experience dictates to improve performance?
The strange thing is that Ubuntu System Monitor says only one core is at
100% full capacity but the other is only 20%. Ans memory usage is only
700Mb, so whats causing all this lag and slow calc, the bar almost dont
moves? Im using Ubuntu 10.04 32bits.

Thank you
Nuno
