Ever hit Run on your Simulink model… and then had enough time to make coffee, scroll Instagram, and maybe rethink your life choices? Slow simulations are painful.
Enter Performance Advisor—your model’s personal speed coach. Think of it as the friend who says:
“Maybe don’t wear boots when running a marathon.”
What It Does (Without the Jargons)
Performance Advisor basically:
Spots bad settings that slow you down.
Suggests better ones (and can even fix them for you).
Checks if your changes actually helped.
Keeps receipts in the form of HTML reports.
It’s the trainer and therapist rolled into one for your Simulink model.
Quick Workflow
Prep your model – make sure it runs, and log at least one signal. No signal, no analysis.
Run checks by simply running the command 'perfomanceadvisor'
Command syntax Take advice – either let it auto-fix or review the suggestions yourself.
Performance advisor window Validate – if the “improvement” made it worse, it reverts to the old settings.
Report card – you get a neat HTML report with passes, fails, and warnings.

Tips from Experience
Don’t log every signal unless you enjoy long waits.
Use it on top-level models only.
Save the reports—they’re handy for tracking changes and proving progress.
Final Word
Performance Advisor won’t turn your model into lightning overnight, but it will help you fix bad habits and find the fast lane. The next time your simulation drags, don’t just sit and wait—let Performance Advisor show you where to cut the slack.
