Dear All.
I've a long rendering time problem.
Here is my setup condition.
1. Server : Postgis and tomcat at the same box, 1Gbyte RAM
2. Data :
2.a The Total data is about 380434 rows (estimated by PgAdmin)
2.b data is splited into 5 different views, based on "level" coloumn value.
3. Layer :
3.a I created 1 layer for each pgsql view
3.b Specific sld for each layer
3.c Each sld have up to 4 rules, based on Scaledenominator.
4. Map display box :
4.a width: 512px;
4.b height: 512px;
4.c border: 1px solid #ccc
5. HTML:
My HTML is jus displaying Googlemap (ROADMAP) , plus 5 layer created in
step#3
There is -->
var options = {
projection: new OpenLayers.Projection("EPSG:900913"),
displayProjection: new
OpenLayers.Projection("EPSG:4326"),
units: "m",
numZoomLevels: 20,
maxResolution: 156543.0339,
maxExtent: new OpenLayers.Bounds(10325843.277142,
-1394213.708171, 16871298.882086, 1110474.834229)
};
===============
And at the end part -->
var point = new OpenLayers.LonLat(110.3667, -7.8000);
// Need to convert zoom point to mercator too
point.transform(new OpenLayers.Projection("EPSG:4326"),
map.getProjectionObject());
map.setCenter(point, 19);
=================
Before I load the html, I open a terminal at the server and do :
---> b...@erp:/var/lib/tomcat6/webapps/geoserver/data/logs$ tail -n0 -f
geoserver.log |grep "done"
Back to my firefox and load the html
The Googlemap loading is fast enough (For me), but the WMS rendering
part is so long.
Back to the terminal and Copy paste the terminal output , and voila .....
6.a there is 210 time of "Writing png image", and
6.b Verry long time :
First writing is at :
6.b.1 2010-09-30 09:23:11,289 DEBUG
[org.vfny.geoserver.wms.responses.map.png] - Writing png image ... done!
Last Writing is at :
6.b.2 2010-09-30 09:31:08,168 DEBUG
[org.vfny.geoserver.wms.responses.map.png] - Writing png image ... done!
Note : The Complete output of the "grep" process is posted at
http://pastebin.com/nxXrXBDh
With all the process , it only need to display one-object of Postgis
It's showed at http://i54.tinypic.com/qxkynp.png , the bold text under
the cursor ... it's a label of the only point that need to be displayed
by the HTML.
Question : Is it normal that this operation take almost 8 minute
processing time ?
Did I do something wrong ?
Kindly please give me your enlightment
Sincerely
-bino-
