Kris,
GeoServer will reproject on the fly if the output CRS differs from the
input CRS, but will get your database to do it if it can. This is
usually quite fast. Rendering can often be more expensive.
You probably want "Declared SRS" EPSG:26915 and "Force declared". See:
http://docs.geoserver.org/latest/en/user/data/webadmin/layers.html#coordinate-reference-systems
Clients can request EPSG:3857. By requesting data, do you mean data as
in WFS or WMS GetFeatureInfo, or did you mean maps like WMS GetMap? For
faster maps, use a tile cache such as the embedded GWC.
Kind regards,
Ben.

Hello,
I have, what might be, a basic question.
I am loading a number of layers into geoserver that have a "Native SRS" of
EPSG:26915.
I am attempting to optimize serving these layers for use in a web mapping
client (ie. leaflet, openlayers) as WMS and WFS requests. I, therefore,
presumed that I should set the "Declared SRS" to EPSG:3857 (and "SRS
handling" to "Force declared") since that is what the web clients will use.
However, while trying to use the "layer preview" in Styles I ran up against
this known issue: https://osgeo-org.atlassian.net/browse/GEOS-8016
So, my question is what should I do to optimize these layers to handle
requests looking for data in EPSG:3857?
On a related note, does Geoserver re-project layers on-the-fly when serving
out data that differs from the "Declared SRS"?
Thank you for your patient explanations.
