[Qgis-user] Qgis slow start up

[Marco Hugentobler]

Hm, on my laptop with ubuntu 9.10 and  current QGIS svn version, 
dcua_qgis140_relative_reduce6_1440x900_17.qgs opens in 3 seconds and 
dcua_qgis140_relative_reduce6_1440x900_19.qgs in 4 seconds.

Maybe William or Tom could test it on Mac and check with a debugger where it 
spends the time (if it does)?

Probably also important is what GDAL version you are using (in my case it's 
the current svn version of GDAL).

Regards,
Marco
