I am the author of the original blog post - https://blog.clevertap.com/sleepless-nights-with-mongodb-wiredtiger-and-our-return-to-mmapv1/ https://blog.clevertap.com/sleepless-nights-with-mongodb-wir... and I handle the dev ops at CleverTap. I wanted to make a few clarifications about the article: Firstly, the original article mentioned 18K operations/minute per node. This was a publishing mistake. We actually do 18K operations/second (the graph on the original post has the numbers as reported by MMS). Sorry about this :( We've posted a couple of updates on our blog, in case you're interested in following this through. And yes, we did file a bug report with Mongo.
