My loader is able to load every page in my copy of XE and they all pass the .equals( test against the same page loaded by the default loader so I feel that I'm ready to publish some tests.
These are time results (in milliseconds) for loading a page containing 1000 comments. see: http://jira.xwiki.org/jira/browse/XWIKI-2874 My test script runs the tests 30 times interchanging old loader and new. These tests were all the first call to a newly started server, you can see it speed up as the code is jit compiled. Conclusion: 850% improvment can be expected for loading a page with 1000 comments. StringListProperty and LargeStringProperty being mapped to the same column costs about 100ms for the workaround, disabling this workaround brings it to an even 1000% speed increase. Disabling custom mapping saves a whopping 8ms. This surprised me. My loader is only marginally faster at loading all of the pages in XE, it is best at scaling with lots of objects. This didn't surprise me. The actual test results are below. Caleb James DeLisle test1: no special optimizations.
