I'm not sure what would constitute a low vs. high hit rate (and eviction rate), so we've kept the setting at LRUCache instead of FastCache for now.
But I will say we did turn the LazyFieldLoading option off and wow - a huge increase in performance on the newer nightly build we are using (the one from Feb 2, 2012). The payload of 13.7 MB that was taking from anywhere around 15-17 seconds (with fastvectorhighlighter on) and 33+ seconds with FVH off is now taking just about 3.2 seconds with FVH on. When we implement the wildcards for the fieldlist, thereby reducing the payload down to 1.9MB, our average return time is around 875ms, down from anywhere around 6-8 seconds before. Granted, I've only run about 20 tests (manually) at this point, so I'm going to keep hitting at the server for a while with different queries to see if anything gives, but at least at this point, it does appear setting the lazyfieldloading to false has improved performance. It'd be ideal to figure out why that's the case, but that's a little beyond my skill set at the moment. I'll let you guys know how results look as I proceed throughout the day. (I've yet to run these tests against the 2010 build we were comparing against - so I need to do that too) Please also let me know if you have any further suggestions.
