If you’re a software developer, then you would know that latency is one of the most annoying problems to deal with due to the fact that there are many variables in play. Fortunately, if you develop in linux, you’re in luck. Intel has released a tool called LatencyTOP, that basically allows you to visually track down what exactly is creating the latency.
This can be done on a system or process level, so you can see for yourself as to which processes are lagging behind so that you can track down the source of the issue and optimize out the lag. And less lag means faster programs.
