Hi Bernhard<br>
<br>
That option was meant to give the webclient a hint where to
zoom first. But it probably was forgotten in the server and
I agree it would be good to overwrite the calculated box in
the toplevel group.<br>

Hi Marco,<br>
<br>
I have a question in this context (I thought I made
ticket but cannot find it)<br>
What is the sense of setting the bounding box in OWS
tab if it is always calculated to the sum of the
bboxes of the layers in the project? IMHO setting the
bbox in the project properties should override any
calculation result.<br>
Background: One of my layers became empty because a
user deleted the last record thus its bbox was
calculated to be the whole earth resulting in QGIS
server propagating the whole earth as bbox for this
project.<br>

Hi Andrea, Giovanni<br>
<br>
QGIS Server doesn't calculate the bbox itself, but
it queries the extent<br>
from the layers. So it can be that certain providers
calculate the bbox<br>
(of course only if the layer / capabilities document
is not cached).<br>
<br>
For a faster startup, having a persistent cache as
Giovanni suggested<br>
might help.<br>

I don't understand why the qgis-server eed to
calculate always the<br>
bbox.<br>
In the server project windows,<br>
qgis ask for the published bbox.<br>
Why it don't use it as bbox rather than
calculate it on every<br>
request ?<br>
<br>
<br>
Marco, correct me if I'm wrong.<br>
QGIS Server doesn't calculate the BBOX, it parses
the layers extents<br>
from the .qgs project and then combine them to
obtain the entire BBOX.<br>
The only operation it does is reprojecting the
extents to WGS84 to<br>
create the EX_GeographicBoundingBox element.<br>
<br>
Anyway, in case the project advertises and extent,
the combined extent<br>
won't be calculated, so in your case this phase
shouldn't be the<br>
bottleneck...<br>

The FastCGI don't help really.<br>
In a publishing environment every few hour the
instances are<br>
restated to removed zombi process.<br>
This mean that every few hours the FastCGI are
emptied and reloaded.<br>
A fastcgi environment mean to load 20
instances of QGIS-server and<br>
every of them do them own elaboration .<br>
As the bbox calculation for every layer.<br>
<br>
GASP.<br>
The start could ask about one hours and more.<br>
<br>
Also another problem with the fastcig is that
when<br>
I change something on a project I need to
restart to Web instances<br>
to dismiss the actual project and reload the
new.<br>
<br>
So every change in a qgis project need a
restart of all proccess<br>
(20 and so on in a fastcgi enviroment) every
with a slow bbox<br>
calculation phase.<br>
<br>
mmhh...<br>

Hi Andrea<br>
<br>
<br>
>I suspect that QS try always to
recalc the box of every<br>
layer.<br>
<br>
QGIS server caches layers (up to 100,
but that can be<br>
enhanced using the environment
variable<br>
MAX_CACHE_LAYERS). Furthermore, the
GetCapabilities<br>
documents are cached (so no
recalculation if using FastCGI).<br>
<br>
<br>
Thanks Marco, you confirmed what I told
Andrea.<br>
It would be a good enhancement if caching
could be done in a<br>
persitent manner (out of memory). We could
consider, in the<br>
future, to use memcache or something
similar.<br>
