This document appears to be a presentation in a foreign language (not English) about performance bottlenecks in Elixir applications. It introduces the presenter, Alexey, and mentions that while Elixir has advantages over JavaScript for asynchronous programming, high loads can still cause performance problems. It concludes by thanking the audience and providing Alexey's contact information.
