Re: [Geoserver-users] Response time of WMS-Requests with PointSymbolizer ExternalGraphic Format image/gif or png sometimes extremly slow

2018-11-13 Thread Blome, Guido (62-24) 
Hi Andrea,

yes we have a xmx setting of 8G. A gc problem was my first thought too,  but 
the Total time threads are stopped by the gc are normaly 30 ms and the slowest 
100 ms. The whole Application Time of the gc is varying between 7000 and 1000 
ms.
During that operations Vektorlayer are serverd with a constant response time of 
~ 90 ms.  There are no breaks with 5000 ms.
Assuming the problem is a gc Problem, why are only PointSymbolizers with gif or 
png showing outbreaks in Request durations with 5000 ms and PolygonSymbolizer 
and Raster not ?

Cheers, Guido

Hi,
weird... it might be a garbage collection related issue... did you give 
GeoServer a very large heap, e.g., more than 4GB?
In that case you might have to tune the garbage collector to reduce GC pauses, 
they can get pretty long with a large heap.

I did a quick test with multiple requests locally, with a style using a PNG 
external graphic, the slowest one is 30% slower than the fastest one.

We are using those WMS symbol layers as overlays on top of WMTS/TMS, delivered

I have tested the behavior with Oracle Corporation: 1.8.0_171 (OpenJDK 64-Bit

Does someone know how we can turn of those 5000ms responses ?
Where does this behavior come from ?

2018-11-13 Thread Andrea Aime 
Hi,
I have no quick answer to that, it would take some analysis with a profiler
(as said, not happening on my machine, even using an external graphic).
If you're in quick need of help I'd suggest to check
http://geoserver.org/support/

[Geoserver-users] Response time of WMS-Requests with PointSymbolizer ExternalGraphic Format image/gif or png sometimes extremly slow

Hi List,

we have published several WMS layers with Point Data out of a

In most of the requests they are working very fast with response times between 
12- 50 ms but every tenth  thirtieth Request, in a Scenario with one request 
per second, there is a response time of ~ 5000 ms with the same or similar
