Talk Title: Case Study: Optimizing a Synchronization Bottleneck with Template Metaprogramming

Description
Synchronization bottlenecks are notoriously hard to eliminate. Modal behavior in systems with synchronization bottlenecks is highly undesirable because it leads to a situation where system performance degrades sublinearly, often even reaching inflection points. In this talk, we'll go over some examples of these bottlenecks, how it led to whole system failures. Then go into detail of how these bottlenecks behave, and how we eliminated some of these bottlenecks with an improved mutex that uses template metaprogramming to make smarter synchronization decisions.
