Ftrace: The hidden light switch [LWN.net]
You may think, as I did, that analyzing the Linux kernel is like venturing through a dark dungeon: without the addition of advanced tracers like SystemTap, there's much that can't be seen, and can only be inferred. However, I've recently found hidden switches that turn on some bright lights, strategically placed by Steven Rostedt and others since the 2.6.27 release. These are the ftrace profilers.

This is a very long transcript for a very long talk. The talkâ€™s running time is close to 120-150 minutes, and transcript may take even longer if digested thoughtfully. Please plan your reading accordingly. There are five large sections which are mostly independent of each other, that should help to split the reading.

JIT compilation in modern platforms â€“ challenges and solutions
This document discusses just-in-time (JIT) compilation techniques in modern runtimes. It outlines two main approaches to JIT - method-based compilation and tracing JIT. It then describes specific techniques used in the HotSpot JVM, including its fast interpreter, two-tiered JIT compilation, runtime profiling, devirtualization, incremental compilation, on-stack replacement, escape analysis and scal

Understanding JVM Internals | CUBRID blog
Every developer who uses Java knows that Java bytecode runs in a JRE (Java Runtime Environment). The most important element of the JRE is Java Virtual Machine (JVM), which analyzes and executes Java byte code. Java developers do not need to know how JVM works.Â So many great applications and libraries have alreadyÂ beenÂ developed without developers understanding JVM deeply.Â However, if you understan
