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.
