Helena,

I just made a test with lidaratm2.txt.gz from
http://mpa.itc.it/grasstutor/data_menu2nd.phtml

wc -l lidaratm2.txt
1158424 lidaratm2.txt

(-> 1.1 Mio points)

cat lidaratm2.txt | time v.in.ascii -z out=mypoints zcol=3 catcol=0 fs=',' columns='x double, y double, z double'

It's acceptable (since you have to do it one time only).

Did you try
 s.out.ascii file | v.in.ascii ... ?
