Do I need template cache if I am using Redis?

[SJ77]

I noticed there was an option it the ACP to cache template files to disk.

• What exactly does this do? (please don't say "it caches your template files")
• Do I still need this if I am using Redis to cache stuff?

Thank you 🙂

It...caches template files to disk. The PHP code is normally loaded up into memory and eval'd, but this option will cache the files to disk and then pull the file in to execute it. You can measure before turning the option on, and afterwards, to see if it really makes any material performance difference in your case.

Using Redis or not is largely irrelevant to whether the feature will improve performance.
