Hi,

the number are ok in my opinion. I assume you don't have an SSD disk, so times will be a bit slower than with a modern PC with SSD. Then 20 plugins activated are kind of a lot. I usually have fewer plugins activated. You also see that 30s out of the 50s are spent on loading the plugins. So if you want to speed up QGIS start you better deactivate some plugins you don't need.

So to me it seems like there are no immediate actions needed from the QGIS team because of slow startup.

The other fact, that repeated loading of programs are faster than the first after a boot - this seems normal to me and I observe this with a lot of other software (e.g. Adobe software) as well. It is probably related that some base libraries are already active or loaded.

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..
