[Qgis-user] Re: Qgis first startup is slow

[Rahkonen Jukka]

Hi,

Here are some more timings.

- Installed 1.8.0-20 with OSGeo4W installer.
- Deleted .qgis directory
- Started 1.8.0 once
- Power off - reboot
- Start QGis from a situation which I believe to be rather clean and no other programs running.

This was a 2004 model PC with Windows XP, 1 X 3 GHz Xeon , 2 GB of memory and IDE disks

Total times from start
47 seconds before seeing Lisboa splash screen  # this feels odd to me, is OSGeo4W doing some initialisations of what?
57 checking provider plugins
1.20 starting Python
1.30 restoring loaded plugins
1.45 ready

A little bit uncontrolled previous test without deleting .qgis directory and power off and some other programs running showed the initial startup time of 3 minutes and 50 seconds. That was much more than with 1.9.0 but as I told, test was not well controlled.  I had pretty many Spatialite databases in the datasource list and I wonder if that could have some influence. At least lights were blinking a few times in my data disk units during the QGis startup.

For comparison timings from Windows Vista 32-bit laptop with existing 1.9.0 installation after power off - reboot:

Total times from start
18 seconds before seeing Master splash screen  # rather a long time also on this computer
26 checking provider plugins
41 starting Python
51 restoring loaded plugins
1.02 ready

This one is 5 years old slow laptop.  We do have faster computers here too but as long as they let me keep these old ones I prefer to test with them.

Thats way too slow. There must be something seriously wrong.

Are the same timings for the latest 1.8 nightly?

On my machine (Win7, SSD disk) the first (cold) start is < 10 seconds. Few plugins activated.

I have had the same feeling with Windows XP so I took some timings. I have
QGis 1.9.90 from OSGeo4W and computer is Windows XP SP3.

Fist startup
- 50 seconds before the "Master" splash screen shows
- 60 seconds more and "Checking provider plugins" is ready
- 40 second more and QGIS is started
Total time was thus 2 minutes and 30 seconds.

Next startups
- total startup time between 5 and 15 seconds (10 repeats).
