Armed with the PID, we can proceed with finding out the NICE level, by entering the command below.

Another method of identifying a particular app is by launching the Application Monitor to locate its PID value. Depending on the number of processes currently running, the list could be quite long. Enter the following command to display the current processes running on the computer.ģ.

SEE: Top 20 Apple keyboard shortcuts for business users (free PDF) (TechRepublic) How to identify the priority of a running appĢ. In the examples below, I’ll cover how to identify the current niceness level, how to adjust it for a thread, and how to launch an app with the desired level of niceness. This is achieved with the nice and renice commands, as they report back the current level of niceness assigned and allow for reconfiguration of the niceness on a scale of 20 (lowest priority) to -20 (highest priority), respectively. MacOS’ UNIX foundation allows users to benefit from these performance tweaks by adjusting the “niceness” assigned to a task or application using the Terminal.

SEE: Virtualization policy (Tech Pro Research) And while modern operating systems and their applications perform this feat efficiently, users can further manage how CPUs process data by controlling how these resources are allocated to apps or, at a granular level, to individual threads. The higher the CPU priority usually the faster the task will complete, and the converse to this applies as well.Ĭomputers process data–simply put, it’s what they do.

Activity Monitor ignores this and does not correct its CPU values to account for frequency changes.įor now, Apple has not reacted yet to this discovery which has probably already had consequences in the development of many macOS applications optimized for Mac M1.One of the most common and biggest trade-offs to higher performance is time that is, the time it takes to complete a task is typically disproportional to the amount of processing resources allocated to said task or application. Although this is complicated, the effort is worth it: with a single thread, the E cores operate at a frequency of around 972 MHz, but with two threads this frequency increases to their maximum of 2064 MHz. To find out how Activity Monitor arrives at these erroneous results, you need to run the powermetrics command tool to find out the frequencies at which the two E-cores were spinning, and their actual power consumption. So running twice the amount of code on E cores alone takes the same amount of power, according to Activity Monitor. Running two threads has a total energy of 1940, at 970 per thread. The single thread has a total energy of 1931 units.s, at 1931 per thread. Here are my results:ġ thread on 2 E cores took 19.5s, at 98% CPU and 99 power value.Ģ threads on 2 E cores took 10.0s, at 194% CPU and 194 power value. Then repeat the operation with two threads imposing the same computational load. Then repeat the operation with two threads imposing minimal QoS. With an application like AsmAttic, run a single thread with minimal QoS so that it only works on E cores.
