Testing the MongoDB Global Write Lock Improvements

Posted by Unknown on from the heckling-haskell-hackers dept.

rick446 writes "I took some time to benchmark the global write lock improvements in MongoDB 2.0. From the article: 'MongoDB, as some of you may know, has a process-wide write lock... 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.'"

    I realize it's not widely known in the west, but it's an important database in Mongolia.

    It's great that they improved the locking. I just hope they didn't compromise web scalability in the process.
