Hi Chris,
Do you run Geoserver under Tomcat?
If yes, you may want to to try (even for testing only) to run the standalone
version with http redirect to port 8080.
Tomcat can be quite slow when dealing with large amount of data.
Cheers,
Zvi

It's hard to say what makes such a setup slow. It may be loading the layers
(each one is checked,
to make sure we can connect to its data source), users as you say, GWC doing
its startup checks
layer by layer...
The startup of such beast would have to be profiled using yourkit, and then a
few days of developer time
would have to be probably spent optimizing bits here and there.
Actually, maybe you could do a simple profile yourself using visualvm, you
cannot exactly
profile it from the very beginning, but since it takes 40 minutes, you would
not lose much.
You have to start visualvm on the same machine as the geoserver, attach to the
process
running GeoServer, and start the profiler, let it accumulate data for a while,
and send us
the results.
Maybe try it a few times until you're comfortable and quick enough to catch it
from within
the first minute from startup.
The visualvm site has some instructions on this:
https://visualvm.java.net/profiler.html
Cheers
Andrea
