Websites today have so many features that performance is always a concern. All we know, that users don’t like slow sites, so your goal should always be to look for ways to speed up Magento 2 across a variety of conditions and devices.
So what are the best ways to speed up Magento 2?
Step 1 — Upgrade to Magento 2 if you’re still running Magento 1
All we know that there are some challenges with Magento 2 migration. But the performance benefits are hard to pass up. Magento published a white paper titled “Site Performance and Scalability Optimizations” — it includes detailed explanations on software architecture differences, caching, and other optimizations.
The following information is from a Magento white paper on improving performance and scalability.
Magento 2.0 outperformed its older counterpart across all use cases:
1. Magento 2 processes 39% more orders per hour, reaching up to 2,558 orders per hour;
2. it delivers nearly instant response times for catalog pages;
3. it enables up to 66% faster add-to-cart server response times that are under 500 milliseconds;
4. it provides 51% faster guest checkout response times and 36% faster customer checkout response times for all checkout steps combined.
Step 2 — Make sure you’re following the Magento Performance Best Practices
Magento 2 documentation has a special section titled Performance Best Practices. This is an invaluable resource for improving page speed. It includes Magento performance tips, hardware/software recommendations as well as best practices for configuring your store.
Step 3 — Choose the right hosting provider and plan
There are things you can skimp on, but hosting isn’t one of them. There’s no way you can have a fast site with a cheap hosting provider. Make sure you choose a hosting plan with solid-state (SSD) hard drives and at least 2GB of RAM. The exact requirements will vary depending on your store. And if you’re choosing shared hosting or virtual private hosting, server location should be taken into account.
There are four main types of web hosting options:
1) Shared Server Hosting – A beginner’s best friend;
2) Virtual Private Server (VPS) Hosting – Shared hosting on steroids;
3) Dedicated Server Hosting – Enterprise-level hosting;
4) Cloud Server Hosting – Web hosting of the future.
Step 4 — Increase “cache” flow
Cache is a way to pre-load web pages or parts of a web page for faster content delivery and faster loading. Essentially, when you open a web page, the server has to figure out how the page should look. Cache pre-loads elements like text and images so that the server doesn’t have to go through the calculations again. Since there are fewer server requests, you get faster load times. Your caching strategy should be aligned with your store. For example, if your related products block has dozens of attributes per product (which the database has to sift through), that block will load slowly. Magento recommends using Varnish and Redis in tandem. They are caching solutions that perform similar tasks. They cache parts of your website (what the users see) and the backend (what the developers see).
