[Qgis-user] Qgis slow start up

Using Qgis 1.4.0, for Mac OS X 10.6, downloaded from http://www.kyngchaos.com/software/qgis I find that, at start up, the .qgs project file for my 70 MB GIS project keeps the CPU 99% busy for 4 minutes, the .qgs project file for my 700 MB GIS project keeps the CPU 99% busy for 8 minutes, and the .qgs project file for my 4000 MB GIS project keeps the CPU 99% busy for 25 minutes. William Kyngesburye reports similar results starting up my small Qgis project with Qgis 1.4.0, under Mac OS X 10.6. Craig Leat reports that his .qgs project files regularly take 25 minutes to start up, under Ubuntu. In a particularly good piece of news, Giovanni Manghi reports starting up my small GIS project with Qgis 1.4.0 takes only 4 seconds, under Linux, which is more than 60 times faster than I am experiencing.

For all of my QGIS projects, I observe that AFTER start up, Qgis QUICKLY pans, and zooms in and out. ESRI ArcGIS starts up all of my GIS projects in less than 10 seconds.

This slow start up by Qgis 1.4.0 is the last remaining obstacle preventing me, and others, from adopting, and promoting Qgis. My small Qgis project can be downloaded from http://homepage.mac.com/gregcoats/jp2/images/dcua_reduce6_01.zip
I will provide $1,000.00 for a verifiably solution that yields start up times from .qgs project files of no more than 30 seconds, delivered this month, and $500.00 for a solution delivered next month.
