Vert.x, Cassandra, Gatling, Twitter, Apple: all these softwares and websites renowned for their high traffic performance share one thing in common.
They stand on the shoulders of the same giant: Netty (https://netty.io/).
Netty is the #1 IO framework for the JVM, yet, it's not widely known and is perceived as very low-level specialists-only.
This talk will let you discover the different strategies Netty has implemented to achieve such amazing performance: allocations, native libs, micro-optimizations, context switching, etc.
