10gen has been doing MongoDB events for years now, and I have attended quite a few of them. The events have always been great. However, I have to say this years MongoNYC was particularly amazing.
ObjectRocket Founder, Kenny Gorman, presents a deep dive into the MongoDB profiler. The MongoDB profiler is a powerful tool for analyzing and improving performance on a MongoDB system. He will show everything from the very basics to advanced usage. He will cover how to use the Aggregation Framework in conjunction with the profiler, profiler analytics, query tuning, and response time analysis.
