You should probably partition the stores/layers in different workspaces,
and use the worskpace specific
OGC services.
The other thing that slows things down is that for each time enabled layer
a query is done against the
database to retrieve fresh time values... we don't have a way to register
them statically, but
I'm thinking that one potential improvement to GeoServer (which requires
coding) could
be to submit these lists to some caching, so that they are not requested
every time (pretty much
like we cache the structure of feature types today).... the significant
downside of this approach
is that the list of times can be very large, caching it would eat memory
easily...
Cheers
