v.support VERY slow

[Eric Kostello]

The subject is really:
v.support is very slow even on a Sparc 2 on files derived
from Los Angeles County TIGER Files....

I imported the Los Angeles County TIGER file with v.in.tiger
then ran v.support. The tutorial for "TIGER in GRASS" warns that
this may take up to several hours, but it has taken nearly 48
hours and it's still not done.

System Configuration:
Sparc 2, 48MB RAM, Plenty of disk space.
Running under OpenWindows

It wrote the file la.Master after about 30 hours in the dig_att
directory.

What I really want to know is whether this is normal for huge 
(e.g. 65MB for type 1) TIGER files or if something has gone 
awry. I'm a new GRASS user and we just got GRASS running here
so there may be some problems with our configuration.....
Any advice on this will be greatly appreciated.


Thanks.
