The optimal solution is to create a TMS/WMTS and serve that. Simone’s linked file is an excellent starting place for optimising your rasters.
See: http://maps.warwickshire.gov.uk/inspire for our implementation - the “Ordnance Survey - Rasters” basemap is similar to what you want I think. As you can see it is highly optimised.

At last I have created GeoWebCache data directory as its mentioned in Geoserver guide pdf, Now its seems to be working good and some test cases also gives the positive results.Anyway I have to test it more. As per your instruction I have tried with imageMosaic. Is it better to use imageMosaic instead of grouping all layers (around 20 GB data)? performance wise?
Ok thanks a lot for your valuable response Simone. I shall do it as per the slides which u gave and come back.
Subversion Kills Productivity. Get off Subversion & Make the Move to Perforce.
With Perforce, you get hassle-free workflows. Merge that actually works.
Faster operations. Version large binaries. Built-in WAN optimization and the
freedom to use Git, Perforce or both. Make the move to Perforce.

Ciao Venky,
well, the HW is ok, about the steps to take, I believe it is pretty clear from the slides where you can also find some sample gdal commands to perform.
Please, experiment a bit with the commands proposed then come back to us with more specific questions.
There is quite some documentation if you search on the web.

Hi Simone,
Sorry In previous mail I indicated that I didn’t get your question.
What is mean by HW? characteristics?
I am using Tomcat 7, JRE 6, Java Heap Size 2GB (Ram 4GB)
I go-through that slides which gave to me.But I dont know what step should I take for preprocessing the tiff images / what type of raster should I use?

Ciao Venky,
I suspect that the HW you are using can’t keep up with the load.
As I asked before, what are the characteristics of the HW you are using for GeoServer? Which Java Options are you using in terms of memory for GeoServer?

Simone Giannecchini

Thanks Simone…I shall do it…but I have doubt why default sample mosaic also not serving for more users from Geosever?

Ciao Venky,
I checked quickly what you are doing and I am pretty sure you are going down a wrong path.
Most important thing to do when you are working with raster is to first optimize the data you are going to serve.
As a newbie, Take a couple of hours to check the recipes contained in the slides I gave you. I believe you should preprocess your tiff files and then look into a different way for serving them,
via as an instance the ImageMosaic.

Dear All,

I have created the layer group by above images(around 76) and that Geoserver preview link is:

@Simone: I am a newbie. I didnot get your 1st point. For 2nd point, I did not use any complex structures in getmap request and did not use any reprojection also.
@José Carlos Martínez Llario: Yes I have used GeoWebCache and checked the GeoWebCache demo. But in the case of concurrent
access, Its failed to server the data for more users.
I have configured the gridset for EPSG:404000, GeoWebCache,Production environment settings, heap size for tomcat…etc
But no result.
We tested the “states”,“tiger_roads” ,and “sample_geotiff” datasets from the GeoServer release configuration with Apache Jmeter ( http://www.guru99.com/jmeter-performance-testing.html) as they said in below links**.**
http://geoserver.org/display/GEOS/Stress+Testing
http://geoserver.geo-solutions.it/edu/en/adv_gsconfig/jmeter.html
Just loading working of those data are working fine as they said for more users. But with zoom in,out,pan and feature info cases, its not able to response for more concurrent users. So we have faced this issue on default Geoserver layers itself as shown in below screenshot.

Please let me know if I have missed any configuration or something and share your solutions. It will very much helpfull to me to fix this. Thanks in advance.

-2- Did you optimized data? Check these slides for some additional

Dear All,
I have developed a web map application by using Geoserver 2.4.0 and tomcat 7
in Windows XP. My problem is geoserver itself not serving the data for
concurrent users around 10 to 15 people (Hanging,Not loading…etc). Its
serving data only for 3 to 4 users.
I did all performance tunning in Tomcat and Geoserver as indicated in
production environment.This is the link I have tested for concurrent access.
http://xxx.xxx.x.xxx:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=Oxford_Map&styles=&bbox=0.0,0.0,700000.0,1300000.0&width=1250&height=800&srs=EPSG:404000&format=application/openlayers
From above link Oxford_Map is the layer group which contains 76 tiff images
with size of 170Mb.
Server configuration is:
Windows XP
Ram 4GB
Geoserver 2.4.0
Tomcat 7 (Heap size 2GB)
Kindly let me know to the solution to speedup the Geoserver. Thanks in
Advance.
