Mailbox has grown unbelievably quickly. During that growth, one performance issue that impacted us was MongoDBâs database-level write lock. The amount of time Mailboxâs backends were waiting for the write lock was resulting in user-perceived latency. While MongoDB allows you to add shards to a MongoDB cluster easily, we wanted to spare ourselves potential long-term pain by moving one of the most f

By David Mytton, CEO & Founder of Server Density. Published on the 23rd May, 2012. Perhaps the most oft-cited problem with MongoDB is the infamous global lock. In general terms, this means that the entire server is locked when you perform a write operation. This sounds bad but is actually blown out of proportion compared to the real world in production impact. It has been improved over the version

Over the last two or three years we have been using MongoDB in some mid-size projects. Now it is time to say goodbye to MongoDB for a variety of technical reasons: the currently memory model of MongoDB based on memory-mapped files is brain-dead. Leaving memory management to the operating is a nice idea - in reality it does not scale and does not play very well. There is no single way to control  t
