Re: [Geoserver-users] Image Pyramid layer settings for faster rendering
Dear Amiala, I thinkl you are on the right track. A few hints: -1- I would make the size of the tiles even bigger than 1024x1024. Make sure to have them internally tiled. In the presentation I attached there are hints on how to do/check that -2- Yeah, the less files in folder, the better. 1 will help with that That said, I would like to see the final properties files that geoserver generates in the root foolder as well as in the top children folder to understand the resolution structure for these layers.

Re: [Geoserver-users] Image Pyramid layer settings for faster rendering
Ciao Simone, What's a great presentation! I found it very useful! I just need to clarify some issues: I have: - 13 levels of ArcGIS Cashed data in .bundle format on the disk. The bigest lever is 18 GB, in total there is 25GB. What I need: - Geoserver Image Pyramid (with 13 zoom level and fast serve for user) What I already did: 1. I converted ArcGis data (accesing it by url as a tile) from .png to .geotiff with .jpeg compression using .geotiff lib (I didn't manage to do it for 2 biggest layers - too many tiles) 2. I used geoserver ImagePyramid plugin (from Web Interface) and create ImagePyramid. Problems: laoding map and zooming (in/out) are too slow What I think after reading your presentation: 1. I need to use UseDirForEachRow option. Now in the last folder I would have more than 16 000 000(!) tiles 2. I need to make bigger tiles (2048x2048 for example) My questions: 1. Do you think I am on the right way now (2 previous items)? 2. If I use "UseDirForEachRow" I will have 4000 folders with 4000 tiles each for the last level, will it help? or it is still too much and I have to find other way.

Re: [Geoserver-users] Image Pyramid layer settings for faster rendering
Ciao Amiala, we would need to have more info about the structure of the data itself: - how many levels you have in your pyramid - the resolutions for each level (you can check the pyramid.properties file for this) - the structure of the data in each level. The gdalinfo on a sample for each level would help I don't remember if I mentioned this presentation but you could find some useful tips: http://goo.gl/TXJRS Regards, Simone Giannecchini == Our support, Your Success!

Re: [Geoserver-users] Image Pyramid layer settings for faster rendering
Thanks, Simone for replay. Data has structure as a ImagePyramid and stored in folders (0,1,2, etc) on the disk. I have Geoserver 2.3, java 1.7 and RAM around 4GB, but geoserver use around 800MB. Now I am already using GWC, but it is still not fast enough. Do you think, the version of Geoserver has a principal influence on the perfomance?

Re: [Geoserver-users] Image Pyramid layer settings for faster rendering
Ciao Amiala, can you please describe a bit more what follows?: - how your data is structured - which version of geoserver you are using - which java opts you are using for starting geoserver - which hw is powering this geoserver instance?

[Geoserver-users] Image Pyramid layer settings for faster rendering
Dear all, I have an image pyramid layer which is working too slow while rendering tiles on the screen. I look at documintation and settings for image pyramid(mozaic) layers. I set AllowMultithreading to true and USE_JAI_IMAGEREAD to false. But still then I am opening it in Geoexplorer it is slow. It is ok for me if at first time loading of the map will be a bit slow, more important if it load fast while zooming and moving around. Should I change some settings? I was thinking that maybe some settings in GeoServer menu "Settings" or "Tile Caching" can help. Could you advice, please, some tricks to make it works faster? p.s. I hope I am posting to correct mailing list :) Regards, Amiala -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Image-Pyramid-layer-settings-for-faster-rendering-tp5072871.html Sent from the GeoServer - User mailing list archive at Nabble.com. -- Get 100% visibility into Java/.NET code with AppDynamics Lite!
