Yes, the question is purely performance-wise. We don't care about any read/write conflicts in this special case. Some time ago, I had some tests with large bulk insertions, and it turned out that SERIALIZABLE seemed to be 30% faster, which surprised us. That's why I ask this questions, and mainly because we currently cannot perform a large bunch of benchmarking. Thanks, Markus -- Markus Schaber | Logical Tracking&Tracing International AG Dipl.
