I turned on --mvcc in the perf tests on January 11. For the most part the changes according to our tests are really minor, +/- 2% usually. The exception is the PPC Mac platform, which had large changes in two tests. Subscribing to collection got about 15% faster, and publishing a collection about 500% (!) slower. Stability wise there does not seem to be a difference to running with or without --mvcc. -- Heikki Toivonen
