Robert, search the archives as there was a recent post about profiling which
will help you identify the bottlenecks. But based on your description and the
fact I know you are on the openlayers list, I suggest you ask there or at least
focus some attention there. I know at the very least you will want to make a
minimal build of openlayers that juts has the parts you need which will reduce
the initial loading time.
I have not gotten to the point of doing any performance optimization yet, but
probably should, so let us know how it goes :)

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
