[Geoserver-users] 2.6.1 JPEG2000 Performance

GeoServer GeoServer User

Hi,

Did anyone notice a significant drop in JPEG2000 performance when making WMS GetMap request? My request format is PNG and tile size is 256x256. I find that it is taking very long to encode to PNG and it took about 4 minutes to get back my image. I didn’t have this problem with 2.5.2.

Thanks,
Danny

You may want to experiment with the “advanced raster reprojection” settings. Try measuring performance with both settings to see if you find a difference. A lot of work has been put into providing you different PNG encoding options so you may wish to experiment on that end as well.

Dear Danny,
can you give us a bit more info as per the following questions?

- provide us a gdalinfo of the input file
- which plugin are you using for serving this file?
- provide us with the config in geoserver for this layer
- which plugin where you using to serve this layer

It looks to me the siutation where GeoServer is not loading a specific
JP2 plugin (ECW or Kakadu) and is actually using the internal JJ2000
one which is _extremely_ slow.
To spot such a problem you need to restart the geoserver with the log
to verbose and look at the plugin that have been disabled. This might
be next step once we get some basic information

Hi Simone,

I played around with the configuration further and I found that the cause of the poor performance is actually due to caching with GWC. I was running GWC with direct integration with GeoServer WMS. When I turned off caching the performance was much better at roughly 10s response time. Is this expected with direct integration with GeoServer WMS? I haven't tried GWC WMS yet.

For information purposes here is the gdalinfo of my input file.

Generally speaking GWC does metatiling when it creates a tile hence
your requests requests a lager area underneath and you also need to
take into account the time to write the tiles to the disk. Then
requests are accelerated on successive access.
You would need to be more specific about what you are doing and how
you are accessing the WMS service in order for me to be helpful.

For information purposes here is the gdalinfo of my input file.

Well, I kind of assume you are using the ECW plugin hence there is no
need to check the logs. Just to be on the safe side in my log I see

An easier way is to check the GUI of GeoServer. When you try to create
a store you need to make sure the right plugin is activated and
available as per the image attached.

One last thing, send over the properties file for the ImageMosaic I
want to see which SPI is suggested (this speed things up as avoids
lookups).

Thanks,
Danny

It looks to me the siutation where GeoServer is not loading a specific

Hi Simone,

I have an image mosaic layer that serves up a global basemap in JPEG2000 format. I am accessing via OWS service with the following sample request,

http://localhost:8686/geoserver/myworkspace/ows?LAYERS=myworkspace%3AJPEG2000_Test&FORMAT=image%2Fpng&MINRESOLUTION=auto&MAXRESOLUTION=auto&TRANSPARENT=TRUE&TILED=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A4326&BBOX=120.76171875,24.43359375,120.9375,24.609375&WIDTH=256&HEIGHT=256

I am also trying to cache the basemap to speed up future requests via GWC. See attached for the image mosaic configuration. I did confirm that ECW is being used. Looking through the log, I found something interesting.

28 Nov 10:29:38 WARN [layer.MetaTile] - ********* Native JAI is not installed, meta tile cropping may be slow ********

Doesn't JAI come with GeoServer?

Thanks,
Danny

Hi Simone,

I played around with the configuration further and I found that the cause of the poor performance is actually due to caching with GWC. I was running GWC with direct integration with GeoServer WMS. When I turned off caching the performance was much better at roughly 10s response time. Is this expected with direct integration with GeoServer WMS? I haven't tried GWC WMS yet.

Generally speaking GWC does metatiling when it creates a tile hence your requests requests a lager area underneath and you also need to take into account the time to write the tiles to the disk. Then requests are accelerated on successive access.
You would need to be more specific about what you are doing and how you are accessing the WMS service in order for me to be helpful.

For information purposes here is the gdalinfo of my input file.

I am using the GDAL plug-in and image mosaic plug-in to serve this layer. See the attachment for layer configuration. Can you elaborate on what keywords I'm looking for in the verbose log? It's quite extensive.

Well, I kind of assume you are using the ECW plugin hence there is no need to check the logs. Just to be on the safe side in my log I see something like this at the beginning:

An easier way is to check the GUI of GeoServer. When you try to create a store you need to make sure the right plugin is activated and available as per the image attached.

One last thing, send over the properties file for the ImageMosaic I want to see which SPI is suggested (this speed things up as avoids lookups).

Thanks,
Danny

Dear Danny,
can you give us a bit more info as per the following questions?

- provide us a gdalinfo of the input file
- which plugin are you using for serving this file?
- provide us with the config in geoserver for this layer
- which plugin where you using to serve this layer

It looks to me the siutation where GeoServer is not loading a specific
JP2 plugin (ECW or Kakadu) and is actually using the internal JJ2000 one which is _extremely_ slow.
To spot such a problem you need to restart the geoserver with the log
to verbose and look at the plugin that have been disabled. This might
be next step once we get some basic information

Hi,

Did anyone notice a significant drop in JPEG2000 performance when
making WMS GetMap request? My request format is PNG and tile size is
256x256. I find that it is taking very long to encode to PNG and it
took about 4 minutes to get back my image. I didn’t have this problem with 2.5.2.

Thanks,
Danny

I want to add an extra note. I noticed that if I don't use integration with GeoServer WMS and directly use GWC WMS (/geoserver/gwc/service/wms), the performance is significantly better. Most of my request response times are < 1s, whereas before using the integrated mode, I was getting some 10s+ response times along with some < 1s response times.

Is there a known performance difference between integrated WMS mode versus GWC WMS?

Thanks,
Danny

An easier way is to check the GUI of GeoServer. When you try to create a store you need to make sure the right plugin is activated and available as per the image attached.

One last thing, send over the properties file for the ImageMosaic I want to see which SPI is suggested (this speed things up as avoids lookups).

Thanks,
Danny

Subject: Re: [Geoserver-users] 2.6.1 JPEG2000 Performance

Dear Danny,
can you give us a bit more info as per the following questions?

- provide us a gdalinfo of the input file
- which plugin are you using for serving this file?
- provide us with the config in geoserver for this layer
- which plugin where you using to serve this layer

It looks to me the siutation where GeoServer is not loading a specific
JP2 plugin (ECW or Kakadu) and is actually using the internal JJ2000 one which is _extremely_ slow.
To spot such a problem you need to restart the geoserver with the log
to verbose and look at the plugin that have been disabled. This might
be next step once we get some basic information

Hi,

Did anyone notice a significant drop in JPEG2000 performance when
making WMS GetMap request? My request format is PNG and tile size is
256x256. I find that it is taking very long to encode to PNG and it
took about 4 minutes to get back my image. I didn’t have this problem with 2.5.2.

Thanks,
Danny
