KTAP: A New Dynamic Tracing Tool For Linux

KTAP is an experimental project that's a new dynamic tracing tool for Linux. KTAP has several different design principles from SystemTap, one of the current most common dynamic instrumentation and tracing tools for Linux. This new project might satisfy some of those developers that have been wanting Sun/Oracle's DTrace to come to Linux.

Hot-Data Tracking Still Baking For The Linux Kernel

A few months ago I wrote about hot-data tracking for the Linux kernel, a VFS feature that could be used by Btrfs and other Linux file-systems for delivering improved performance. Unfortunately the patch-set didn't make the new Linux 3.8 development cycle, but hot-data tracking is still being worked on for merging into a future Linux kernel release.

Linux Dynticks Being Extended For Performance Wins

Dynticks, the Dynamic Tick Timer for allowing the Linux kernel to skip ticks while idling and resume to running at full HZ when encountering load, is in the process of being extended. Developers are working on making Dynticks work even under select workloads in order to enhance the performance of CPU-intensive tasks.
