Organize your database well
Index columns you use a lot

Customer satisfaction	Helps you know if customers are happy

Set up alerts for when things go wrong so you can fix them fast.

Try out high-traffic situations
Test how much your system can handle
Find where your system slows down

Use tools like JMeter or Gatling to test how your system works with lots of users.
