The Morning Paper

JULY 21, 2019

A big milestone will slip quietly by during this recess – it was five years ago on the 30th July 2014 that I read and shared the very first paper in this current streak of paper reading. In case you’re wondering, that paper was " Why functional programming matters " (revisited again on the blog 2 years later).

Before we dive into the differences between MariaDB and MySQL, we will provide a thorough examination of each relational database management system (RDBMS). While originally designed to be a drop-in replacement for MySQL, it evolved into its own distinct database management system and is now maintained and supported by the MariaDB Foundation.

The problem is that this system has a default libc that has been compiled without frame pointers, so any stack walking stops at the libc layer, producing a partial stack that's missing the application frames. This is pretty common and usually goes unnoticed as the flame graph looks ok at first glance. This can be done using eBPF as well.

In late 2014 I was modifying the JDK to preserve the frame pointer so that traditional stack walkers and profilers would work (an example of the problem is here , where Java methods lack ancestry). If you're automating or implementing flame graphs, this is a small detail that may interest you. First, a confession.

After 20 years of neck-in-neck competition, often starting from common code lineages, there just isn't that much left to wring out of the system. Consistent improvement is the name of the game, and it can still have positive impacts, particularly as users lean on the system more heavily over time. Delayed three years [8].

The older Intel Xeon E5-26xx v3 (Haswell) series which was introduced in Q3 of 2014, had a maximum memory bandwidth of 2133MHz. This level of performance compares pretty well to many typical on-premises systems, although it is still pretty easy to have much higher storage performance with a carefully designed on-premises storage subsystem.

That means that when my test program allocates and then frees 1 GiB of aligned executable memory, this leaves 16 MiB of CFG memory allocated. On any modern operating system each process gets their own virtual memory address space so that the operating system can isolate processes and protect memory. That’s unfortunate.
