Hi ! just coming back from a week of vacations...
I have spent some time yesterday analysing the peformances of the BulkLoader. Most of the time is spent in the parsing of entries by the LdifReader class. 25% is spent in the PrepareString method, and 10% in the GeneralizedTimeNormalizer. If we don't call the PrepareString.normalize method, assuming that we don't have special strings, we save around 18%. A faster verison of the GeneralizedTimeNormalizer provides a 9% gain (it has been committed). At this point, the question is to know if we should call the PrepareString methods or not. Not calling it provides a huge speedup, but OTOH, it's an important phase. I'm still investigating some other speedups.
