Hi Justin,
Thank you for the information. I read the link you sent and it was a very good
one.
I am looking at both WMS(50%) and WFS(50%) in each application in a tomcat
environment with maximum simultaneous users about 5-10."For smaller
installations that don't typically handle much load we typically use a vm with
1-2 G of RAM giving about half of it to geoserver."Is this the case you are
referring when you have geoserver as a webapp in Tomcat? Tomcat and Geoserver
both being java based, consume more RAM and you would still suggest 2GB of RAM
with server optimizations? With the above configurations, is 5-6GB RAM with
decent processor considered a safe estimate or an overestimate?
Thanks,
Ravi,

Hi Ravi,
It really depends on what you expect the load to be on the server. For instance
if you only expect the server to be accessed by a handful of users then some
pretty modest requirements will probably work. For smaller installations that
don't typically handle much load we typically use a vm with 1-2 G of RAM giving
about half of it to geoserver. For larger setups obviously the requirement goes
up.
It also matters what type of traffic you will be doing. For instance if you are
strictly doing WMS then the more memory the better since for rendering the WMS
has to continually allocate large chunks of memory for images. Whereas WFS
operates in a strictly streaming fashion.
There is currently an issue as well in that if you have that many
layers/feature
types you will want to change the "feature type cache settings" (global
settings
page) to be larger than the number of layers/feature types.
Also it is important to properly configure the server in terms of limits. You
should find this article interesting:

Hope that helps.
