CZ Podcast 90 — Writing low-latency applications in Java

In my biased view, this was one of the best episodes we recorded all year. If you’re among those who see Java as C++’s slower sibling, this episode will convince you that you can write Java applications that handle requests within a millisecond. Our guest was Karel Rank, who took us through the world of optimization, starting with Java code, through the JIT and the operating system scheduler, all the way down to the CPU instruction set itself. This was definitely our last episode this year, but we’ll be recording another right at the start of the next one.
