Improving website performance
Last updated: November 2022
Select servers with NVMe SSD storage
Using a server with local NVMe SSD storage will yield better I/O performance than network attached block storage, SATA or SAS SSDs or spinning disks.
This is especially relevant if you have a website with large MySQL databases.
Use servers with a modern CPU and high clock speed
The number of CPU cores is important for scaling your cluster however, the clock speed is generally more relevant when it comes to improving a sites speed and TTFB (time to first byte).
Enable opcode caching
Ensure you have toggled opcode caching "on" in the Enhance control panel.
Utilise LiteSpeed / OpenLiteSpeed + LSCache
If you are running WordPress websites, consider switching to LiteSpeed or OpenLiteSpeed and install the LiteSpeed Cache plugin through your WordPress plugin manager. In our experience this can give ~10ms TTFB for cache hits.
You can create hosting packages in the Enhance panel that pre-install the LiteSpeed cache plugin on all WordPress installations.
