Avoid the degradation in performance with the memory eating applications such as Photoshop, Office and iWork. It is a great tool to make sure apps are not eating away the memory compromising the performance. Want a simple user interface in a tool to speed your Mac and stop the memory leakage, then choose Memory Purge. JPerf is a Java-based tool that can calculate the maximum TCP and UDP without any additional hassle or complex settings. The application is a frontend for Iperf, a popular command-line utility.

If you think your Mac might have a hardware issue, you can use Apple Diagnostics to help determine which hardware component might be at fault. Apple Diagnostics also suggests solutions and helps you contact Apple Support for assistance.
Prepare your Mac
- Shut down your Mac.
- Disconnect all external devices except keyboard, mouse, display, Ethernet connection (if applicable), and connection to AC power.
- Make sure that your Mac is on a hard, flat, stable surface with good ventilation.
Start Apple Diagnostics
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Apple silicon
- Turn on your Mac and continue to press and hold the power button as your Mac starts up.
- Release when you see the startup options window, which includes a gear icon labeled Options.
- Press Command (⌘)-D on your keyboard.
Intel processor
- Turn on your Mac, then immediately press and hold the D key on your keyboard as your Mac starts up.
- Release when you see a progress bar or you're asked to choose a language.
View the test results
Apple Diagnostics shows a progress bar while it's checking your Mac:
When testing is complete, Apple Diagnostics shows the results, including one or more reference codes. Learn about Apple Diagnostics reference codes.
To repeat the test, click “Run the test again” or press Command-R.
To restart your Mac, click Restart or press R.
To shut down, click Shut Down or press S.
To get information about your service and support options, make sure that your Mac is connected to the internet, then click ”Get started” or press Command-G. Your Mac will restart to a webpage with more information. When you're done, choose Restart or Shut Down from the Apple menu.

Question or issue on macOS:
I need the “perf” utility to monitor the program on my Mac. I know linux comes with it, but is it available on Mac?
I am working on a OSX 10.9 Mavericks and tried “port search” for perf or linux-tools, but I couldn’t get any results.
How to solve this problem?
Solution no. 1:
As @Sami Laine said in his comment, the Linux perf tool is dependent on Linux specific code. It relies on the perf_event_open system call which is not standardized.
Note: Maybe you could search how MacOSX users are using recent hardware performance counters.
Solution no. 2:
On MacOS you can use the “Instruments” application to profile your code. I like to use the “Time Profiler” which will show you how much time your application is its various parts during execution. I haven’t used perf myself, but from talks/videos that I’ve seen this seems to be the most common use.
To use the “Time Profiler”:
- Run Instruments, select Time Profiler
- At the top left, select your target (executable)
- Hit the Record button on the top left and let it run for a little
while. - Pause or Stop the execution and drill down on your calls in the main
window.
Hope this helps. Android emulator instagram.

On OSX you can use sample together with filtercalltree.
