How to speed up Magento 2 Website? - What are the effective checklist for it?

Please follow the below steps to improve the page speed.

• Enable GZIP compression.


• Use Lazy Loading for images.


• Keep your Magento and 3rd party extensions up to date. Use sprite image instead
  of separate images of small icons.

I hope the above tip will useful for you

Make sure all cache types are enabled (bin/magento cache:status and bin/magento cache:enable if they're disabled). It's faster to flush the cache types everytime you make changes than to have them disabled.

When you're ready to publish your site put it in production mode (bin/magento deploy:mode:set production). This will generate classes and deploy static content - please note that it's hard to make changes (js and css) after this so don't do it unless you're done.

Before going into production mode enable css and js minifying and merging and js bundling (see Stores > Configuration > Advanced > Developer section); please note that this is only visible in developer mode.

Optimize images (I recommend using https://tinyjpg.com/), refractor your code:

• make sure you don't use nested foreach loops


• 
  never load model entites in loops ($product = $this->_product->load($item->getId()) or something like that)


• search throough your layout xml files and make sure there are no blocks with cacheable="false" since this disables caching for the entire page where it is rendered (read more here https://devdocs.magento.com/guides/v2.2/extension-dev-guide/cache/page-caching.html)

This is what came out of my mind, hope it helps you :)
