[Qgis-user] 2.6 very slow to render

[Brett Adams]

Checked out your suggestion Donovan.

 

As it’s a new installation I don’t think external plugins are loaded.  (Guess that’s why I don’t have the qgis2 folder??? )

 

Data storage is small SHP files (100 points) and a series of raster images (300kB).  

 

Same files that were being used in 1.8.

One thing you can check for is if there is a faulty plugin causing the issue.

 

Try backing up your .qgis2 folder (ie, rename to .qgis2.backup)

 

Then relaunch QGIS 2.6 and test again.

 

What's the data storage format? Are they spatialite, postgis, shapefiles, etc?

Seems I spoke too soon.

Removing files from the Layer control takes an eternity

Tried uninstalling both 2.6 and 1.8 and reinstalling only 2.6 but this
doesn't seem to have helped.

Thanks Alex

That made a significant improvement.  I can live with that.

Try disabling/changing multi-threaded rendering. It may not work well on
your hardware.

Settings ->Options->Rendering

Thanks,
Alex
