Therefore, it can cut the page load time by more than 50%.

These are locations in which you can enable cache:

Memory cache stores bits of data generated by apps in system memory, and when the same bit of data is requested, it is served without the need for processing.
OpCode cache is compiled results of previous page requests. Can save several seconds for complex apps like Magento or Drupal.
App cache: Some apps such as Magento and Drupal stores processed template files as pages to reduce processing time. You can use this in conjunction with any of the above caches.
HTTP caches are web server proxies storing all HTML pages. So if the same page is requested, it is served immediately. By far, this has been the fastest and is good for high traffic smaller web apps.

2.4. Monitor Performance

Regularly monitoring server performance is essential for identifying and addressing issues before they escalate. Use performance monitoring tools to track metrics such as CPU usage, memory usage, disk I/O, and network traffic. This data helps in proactive management and optimization of server resources.
