In this talk from the RavenDB conference, Federico Lois is discussing the kind of performance work and optimization that goes into RavenDB.

Performance happens. Whether you're designed for it or not doesn’t matter — she is always invited to the party (and you better find her in a good mood). Knowing the cost of every operation and how it distributes on every subsystem will ensure that when you are building that proof-of-concept (that always ends up in production) or designing the latest’s enterprise-grade application. You will know where those pesky performance bugs like to inhabit. In this video, Federico goes deep into the inner working of every performance sensitive subsystem — from the relative safety of the client to the binary world of Voron.
