I'm evaluating Antivirus software suites for my Mac, and would like to measure the performance impact they have on my computer.
I am not looking to do a expert-level thorough examination, but rather get a crude measure with some snapshot data points (or time-series data if possible).
- What are the main metrics I should monitor? I'm thinking about the application's CPU usage – but is there anything else?
- Is there a user-friendly way to do this (using an application or Terminal tool)?
If there is a general answer that applies to measuring any type of application, perhaps the question title should be changed to “how to measure the performance impact of MacOS applications”.
Note: There are of course a few AV comparison sites out there. But I've been slightly perplexed when looking at their results. For instance, one year ESET Cybersecurity Pro gets a top score in the performance department, but the next year it scores much lower and the article will say that it's a drag on the computer. I gather that one way to find out what works is to test them yourself.
