[geoserver 2.0] ImageMosaic reprojection performance ?
by Yves G
::
Rate this Message:
Hi
I've just installed geoserver 2.0 and I observed a performance degradation compared to version 2.0RC1 when doing wms request of an ImageMosaic layer. The same imagemosaic (prepared with GDAL) is used between the 2 versions. With version 2.0 a request can take 20 seconds in average under linux although the same request is served almost instantly with RC1. However, I see that the image rendered with the final version is in better quality (sharper details). The layer is in EPSG:3296 and the wms request asks it in EPSG:4326, and in logs i see that most of the time is spent here in the reprojection of the raster if I understand: 2009-11-06 09:50:11,020 DEBUG [geotools.rendering] - clonedFinalWorldToGrid AffineTransform[[0.144813403189081, 0.0, -2142.0672896392643], [-0.0, 0.147284057806299, -2016.762187069049]] 2009-11-06 09:50:31,677 DEBUG [geotools.rendering] - Raster rendered Has the gt projection/renderer engine such changed since RC1 to have those performance?

Ciao Yves,
sorry for the late answer. After RC1 we forward ported some ( a lot ) of work done specifically on the ImageMosaic plugin. As part of this work I fixed a bug related to how the overviews were chosen during reprojection; to make it short we were using always an overview 1 level smaller than needed which meant more performance but worse results. That said it looks strange that this accounts for this large difference in performance. I would suggest to prepare a small mosaic, like 2 tiles, which you can share with us in order to make some performance tests and identify the cause for the problems.

Ciao Yves,
we have identified a bug which I think should have caused the performance problems you were experiencing. Long story short, we were *always* using the full resolutions mosaic prior to reprojection. Here you have the relevant jira reports: http://jira.codehaus.org/browse/GEOS-3660 http://jira.codehaus.org/browse/GEOT-2839 Simone. ------------------------------------------------------- Ing.

Hi,
can you please tell me how will this effect 1.7.* branch? That is, was this also the case in v1.7.7 or only for v2? Because I noticed similar changes in mosaic going from 1.7.6 to 1.7.7.

Ciao Ivan,
yeah the bug also effect geoserver 1.7.7 and a fix will be provided for that branch as well. Keep on bugging us about this, as soon as the backport to 1.7.x will be done I'll ask you to grab a nightly to test. Simone. ------------------------------------------------------- Ing.
