Hi,
I am interested in building a web gis portal using geoserver. The portal
will be accessible by different users, who will be able through a treeview
to see different layers. Each layer will have a combination of different
geometries appeared on the map panel.
The data will be stored in a postgis db.
My question is related with the limits of geoserver concerning:
the maximum ammount of features can serve without getting slow.
I've read there are a set of configurations (Java Runtime Environment,
correct projections) to be made beforehead.
Yes and no, those are the ones that you should do last. See this
presentation
for the stuff that actually matters (preparing data and styles):

About the question, how much data before it gets slow, it not only depends
on the data volume, but also how you style it, the data source, and so on.
We often say that if you put more than 1000
items in a map, people won't be able to discern them, the map won't be
readable, so normally one tries to stay below that limit.
Well, unless you're only concerned in showing the distribution of the items,
and not much in having the single item be visible, in that case you can
go higher, up to some hundreds of thousands I guess.
On my old corei7 first generation I can render the full detailed set of
roads in Texas
(almost 6 million roads) in less than 30 seconds. Fast, it is not, but it's
not useful either...
Also is there a maximum ammount of layers you can make in geoserver?
No, there is no limit, but the more layers you pile up, the more time it
will
take to render them, the harder it will get to read the resulting map
Cheers
Andrea
