First, IntroductionSystemtap is an open source software that troubleshoots performance or functionality issues with Linux systems. It makes it easier and easier to diagnose the Linux system at runtime. With it, developers or debuggers no longer need to recompile, install new kernels, reboot, and other annoying steps.In order to diagnose system problems or performance, developers or debuggers only need to write some scripts and then use the command-line interface provided by SYSTEMTAP to diagnose

There are many performance analysis tools on Linux, and a system performance expert, Brendan D Gregg, was found on Weibo, and a talk and slideshow on Linux performance was released at the recent LinuxCon NA 2014 conference. Compared with last year, this year increased the testing and optimization of the two parts. I have been programming for many years, the tools are only used, no in-depth research. Subsequent to these tools into the analysis, the first Guide group of students in the actual proj

The CPU cache query tool in Linux and the cpu cache query in linux In Linux, you can use the following tool to query the CPU cache: Method 1: $ Lscpu L1d cache: 32 K Method 2: $ cat /sys/devices/system/cpu/cpu0/cache/index0/s

Thread Affinity Why thread CPU affinity is required Applications are executed in a multi-threaded manner, most of which can be reasonably scheduled. In some cases, however, an important thread is paused, and the time slice is assigned to an irrelevant thread. When a thread is paused for hibernation each time and is awakened, the cache line (CPU L1/L2 cache) needs to be reloaded. When a thread's working ti
