this from Cloud platforms with very variable Quality of Service and availability guarantees (if any). Yet most engineering teams aren't up to speed with POSIX and POSIX.1b(Realtime-extensions), the API's exposed by most modern production systems for I/O.
In this talk I'll look at a few very often misunderstood concepts, as well as challenge others.
* Understanding buffered I/O and how to sustain throughput for fast and slow clients alike
* Blocking VS Non-blocking I/O
* POSIX Lies - compliance isn't always as it should be, in some cases *worse* than CSS and other specifications "supported" by modern browsers
* Asynchronous I/O myths and why I/O concurrency is often an illusion
* Why and how Windows I/O Completion Ports knock the socks off most UNIX systems
* I/O multiplexing gotchas
* The Cloud: managing latency with variable network and storage characteristics
* High throughput system calls
