I found some slowness in the wizardpagedef/wizardpage loading using a profiler. I made an adjustment to the matrix and wizard hbms and things seem to be much smoother now.

I added some more caching to matrix and wizard hbm's, performance is very good now. Went from 250,000 millis down to under 1000 millis. Sometimes the first hit maybe a little slow (a few secs) if the cache is outdated, but then after that is very quick. So in theory in a use case where everyone is hitting server at same time, one guy will be a little slow, and then everyone else very fast.
