[Qgis-user] table join very slow

[Florent LEVAVASSEUR]

Hello,
I often use table join in Qgis 1.6 on Ubuntu 10.10. It works fine but it 
is very slow for big shape files. For instance, with a shape file with 
about 15 000 lines and a dbf table with the corresponding ID, it takes 
more than 2 hours. Is it normal or am I making something wrong ? For 
small shape files (about few hundred lines), it takes only few seconds.
Thanks for any help.
