[GRASS-user] v.color takes a long time for 2E6 records

[Mehrdad Varedi]

Hi Everyone,

When using v.color on a map with 2 Million points, it takes more than 24
hours (I guess the last time it took near 40 hours). The CPU is busy less
than 20% on a 8 core machine and a lot of memory is available (50% at least
is empty out of the 16 GB). Is there a way that I could accelerate the
processing? Is it normal at all?

Here is the command I am using:

v.colors -c --verbose map=WM195 at Waterlix use=attr column=BRProbH color=gyr
rgb_column=ColorH

Thanks for your help in advance,


Mehrdad
