LKML: Stephane Eranian: [PATCH v7 0/4] perf: add support for profiling jitted code
This patch series extends perf record/report/annotate to enable profiling of jitted (just-in-time compiled) code. The current perf tool provides very limited support for profiling jitted code for some runtime environments. But the support is experimental and cannot be used in complex environments. It relies on files in /tmp, for instance. It does not support annotate mode or rejitted code. This pa

Understanding GC pauses in JVM, HotSpot's CMS collector. Concurrent Mark Sweep (CMS) is one of HotSpot JVM low pause garbage collectors. CMS can do most of its work for reclaiming memory concurrently with application (without stopping it). But still it requires few stop-the-world pauses to make its work. This article will explain nature of these pauses and how to minimize them. HotSpotâ€™s CMS is a
