[Qgis-user] Re: Qgis first startup is slow
Continuing investigations.. Win7 64 bits . icore3 4Go RAM. QGIS versions 1.7.4 standalone or 1.8 RC1 doesn't make any difference. I still have that first slow startup even with Avast antivir disabled. I did a few other tests and I found same behaviour with FME! So it seems related to Windows virtual memory allocating process, or maybe with windows security tools. I then tested without any swap file (pagefile.sys).. It is a bit faster, but slow startup remains. Anyone knows in details how windows allocates memory for a process? It seems Windows dedicates memory space for a process for a while.. I will test it under ubuntu and MacOS then... -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Qgis-first-startup-is-slow-tp4975911p4977128.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Here are the results of a small bench: Qgis 1.7.4 Standalone. Windows server 2003 + citrix XenAPP. It is on virtualized shared servers, though I don't know if servers are really busy or not. 1- Qgis with 20 plugins activated: First startup takes about 50 seconds, and different steps are linear (30 s to restore python plugins) Second startup takes about 15 seconds, and still seems linear. 2- Qgis with *no* plugin activated. First startup takes 20 s Second startup takes less than 4s New behaviour observed today (to be confirmed). I started Qgis and let it inactive for two hours at lunch. I came back, quit Qgis, and startup is again slow. I start up again and it is fast again.. So, I guess there is no relation with session initializing. I'm going to check what's happening with virtual machine underneath..

Hi all, slow startup for me is under windows 2003 server and windows 1.7.4 standalone installer. I don't think this has something to do with OSGEOW.. still strange.. I'll do some bench tomorrow.

Re: [Qgis-user] Re: Qgis first startup is slow
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. -Jukka Rahkonen- Andreas Neumann [mailto:a.neum...@carto.net] 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). -Jukka Rahkonen- Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

[Qgis-user] Re: Qgis first startup is slow
Hi , I have no problem under windows XP. Deleting .qgis folder allows an instant startup. I took care of having really few plugins installed afterwards, and most core plugin are deactivated, but this "first startup behaviour" remains. Does Qgis recompile python scripts at each startup? could it be parsed by antivirus once at start? Still searching.
