Testing the MongoDB Global Write Lock Improvements

Per-database and per-collection locking is on the roadmap ..., but it's not here yet. What was announced in MongoDB version 2.0 was locking-with-yield. I was curious about the performance impact of the write lock and the improvement of lock-with-yield, so I decided to do a little benchmark, MongoDB 1.8 versus MongoDB 2.0.'"

Congratulations. You matter enough to bother reinventing this wheel again. If you continue to matter for a meaningful amount of time you'll end up locking individual documents, or whatever you call them. Oracle called that 'row' locking. 15 years ago.
