Lessons in debugging: observe how programs interact with the Linux kernel with STRACE
There are a subset of problems in software development that can be traced back to system calls or signals. Learn about STRACE, tool that let you trace system calls and signals and that can help you quickly figure out the origin of those problems.
How branches influence the performance of your code and what can you do about it?
In this articles we investigate on how branches influence the performance of the code and what can we do to improve the speed of our branchfull code.
CPU Dispatching: Make your code both portable and fast
CPU dispatchingh is all about making your code portable and fast. We will talk about how to make your detect features your CPU has at is disposal and select the fastest function for that particular CPU without a need to recompile your software.
GDB: A quick guide to make your debugging easier
We will talk about how to profit from some of GDB’s very useful albeit less known features.
Make your programs run faster: avoid function calls
Function calls are not cheap operations and for time critical code it is better to avoid them. This article explores techniques you can use to avoid function calls thus speeding up your code.
FlameGraphs: Understand where your program is spending time
Learn about FlameGraphs, a great tool that will help you quickly find slow functions in your program.
MOSH – a simple SSH replacement that works when network conditions are bad
Connection keeps dropping with SSH? Read about mosh, a simple addition to SSH that can keep your connection survive the rough network environment.
Link Time Optimizations: New Way to Do Compiler Optimizations
Traditional compilation-linking cycle generates binaries that work fine, but in case you need more speed, you need to learn about link time optimizations. Here we talk about what link time optimizations are, how to enable them and what improvements to expect.
Make your programs run faster by better using the data cache
We investigate how the data cache influences the performance of your program, talk about ways for you to write faster programs by better leveraging the data cache.
