24-core CPU and I can’t type an email (part one) | Random ASCII
This investigation included a lot of rabbit holes. Some were important (page tables), some were instructive (locks), and some were purely a waste of time (WMI details). I’ll talk more about these, and a vmmap bug, in a follow-up post. If you want more gory details – some of which ended up being wrong or irrelevant – you can follow the whole investigation at crbug.com/870054.

A Performance Cheat Sheet for PostgreSQL | Severalnines
Performance is one of the most important and most complex tasks when managing a database. It can be affected by the configuration, the hardware or even the design of the system. By default, PostgreSQL is configured with compatibility and stability in mind, since the performance depends a lot on the hardware and on our system itself. We can have a system with a lot of data being read but the information does not change frequently. Or we can have a system that writes continuously. For this reason, it is impossible to define a default configuration that works for all types of workloads.

DTrace for Linux 2016
With the final major capability for BPF tracing (timed sampling) merging in Linux 4.9-rc1, the Linux kernel now has raw capabilities similar to those provided by DTrace, the advanced tracer from Solaris. As a long time DTrace user and expert, this is an exciting milestone! On Linux, you can now analyze the performance of applications and the kernel using production-safe low-overhead custom tracing, with latency histograms, frequency counts, and more.
