Slow convertion to spatialite using "Save as"

[jrm]

Saving a shapefile to SQLite using the right click menu "Save as" is anormally slow, the qgis' process is constantly switching between jbd2_log_wait_commit and blkdev_issue_flush with less than 1% of the cpu. The convertion takes nearly one hour to complete.

Converting the same file with ogr2ogr is taking less than 30sec

ogr2ogr -f "SQLite" ~/rgc2009.sqlite ~/rgc2009.shp -a_srs EPSG:2154 -dsco SPATIALITE=yes

I've joined a test file, steps to reproduce :

1. add the shapefile to a new project
2. right click and Save as
3. choose SQLite and save

Tested with QGIS r15378, on a dual core running Fedora.

It takes 50 minutes to convert, but also more than one minute to display the shapefile, and the process takes on average less than 2%CPU and around 5% memory.
