[Geoserver-users] general considerations about geoserver

GeoServer GeoServer User

Hi geoserver list,

At present i’m working in a great public authority which is provider of several mapbased services. In current redesign considerations we think about replacing the esri based WMS’s by open source WMS and i was using geoserver sometimes and to speak from my own experiences i have to claim, that geoserver does a great job. But for this consideratins i need more hard facts to convince the deciding circle of persons. Therefore here some questions that are relevant for us:

  1. Does geoserver support the use of multiple processor architecture (means is it able to spread its computing activities to multiple cores at high load)?

  2. Does geoserver have a proven parallel processing of simultaneous requests?

  3. Are there research results about the performance of geoserver at a high request frequency?

  4. Is there a list of representative organisations which use geoserver in a productive environment?
    The answers to this questions could help me to introduce geoserver here (so you could add another organisation which use geoserver in a productive environment to the list ;o)

Best regards

Albrecht

Yes, each request is run by a separate native thread

2. Does geoserver have a proven parallel processing of simultaneous requests?

We have run various tests lately and scalability has been, generally
speaking, linear up to the point the parallel requests matched the
number of cpus but I cannot provide any guarantee
A good way to show your users the scalability would be to take JMeter
and run some tests of your own.

3. Are there research results about the performance of geoserver at a high request frequency?

The only published test in english that I'm aware of is this one:
http://www.foss4g2007.org/presentations/view.php?abstract_id=120
(beware, both servers were run with antialiasing disabled to match
the mapserver default behaviour)

4. Is there a list of representative organisations which use geoserver in a productive environment?

I know a number but unfortunately I don't know if I can cite them
publicly. Chris, cc'ed, may provide a list of well known users that
we can cite freely.

Cheers

Hi Albrecht et al,

The following information might contribute to answering question 4. It
comes from Antti Roppola who works for an Australian Governmental
Organisation (Bureau of Rural Sciences).

I hope this helps a bit.

Maybe you can us all by adding the information you collect to the
following wiki page on OSGeo:
http://wiki.osgeo.org/wiki/Case_Studies

Regards,

Roald

Hi Roald,

I am subscribed but rarely get time to browse.

We are implementing Geoserver but it is not yet being used by BRS
in a production capacity. Most of our work thus far is about using
WFS for aggregating observation data than as map rendering engine,
so I'm not the best person to ask about suitability as a WMS engine.

In short:
Things are progressing, but I don't have anything concrete to point at.

Here are some links to published Commonwealth Geoserver deployments
that I am aware of.

Hi Antti,

Not sure if you are on the GeoServer list. Does BRS officially use
GeoServer and could you therefore contribute to answering question 4
from your (BRS) perspective?

Kind regards,

Roald
