In my opinion, WP Rocket (affiliate link) is currently the best caching plugin for WordPress.
It works very well, it offers a lot of useful and important features, and it allows you to get rid of a lot of other plugins.
I’ve been using it for 3 years and I’m more than happy with it!
If you want more details, then here’s my WP Rocket review.
You could even use it on its own if you can’t afford WP Rocket, especially now when they completely refactored it, added numerous new features, and it’s not missing crucial things anymore, such as GZIP compression and browser caching.
While it has become a good caching plugin, it still can’t really beat WP Rocket.
But it does have an important feature that WP Rocket doesn’t, which I’ll talk about below.
So, if you are a SiteGround user, it will be worthwhile to use SG Optimizer in combination with WP Rocket.
And yes, they are compatible.
Using WP Rocket with SG Optimizer
Even if they are compatible, I don’t recommend using the same set of features on both plugins.
And this should be a general rule. Don’t use two or more plugins that do the same thing.
So, basically, all you’ll have to do is to simply enable a caching feature that’s important but missing from WP Rocket.
That feature is called Memcached, which is a memory caching system that speeds up the database queries.
You don’t have to do anything in WP Rocket besides setting it up according to your WordPress website’s needs.
If you don’t have the SG Optimizer plugin installed, do it before proceeding with the below steps.
Go into SiteGround’s cPanel and access the SuperCacher tool.
Disable the Static Cache and Dynamic Cache.
Go to the Memcached tab and turn it on.
Log in to WordPress and go to SG Optimizer > SuperCacher Settings.
Make sure the Dynamic caching is disabled – even if it shouldn’t work if it’s disabled from within the SuperCacher tool – and enable the Memcached setting.
You let SG Optimizer handle the Memcached process while WP Rocket handles everything else.
This should improve your WordPress website’s speed.
If it makes things worse, then you might want to consider disabling SG Optimizer entirely and only use WP Rocket.
As with any caching plugin, a bit of before and after testing is required.
Step 4 – Important!
Except for the Enable HTTPS option (in case it was already enabled and used), everything from Environment Optimization, Frontend Optimization, and Image Optimization should be disabled!
Those settings are normally automatically disabled by WP Rocket, but, to be sure, check them anyway.
Everything there (except for image compression) is offered by WP Rocket, so if you want one of those features enabled, enable it in WP Rocket.
You could enable the New Images Optimization and Existing Images Optimization options if you are not already using another plugin for that (WP Rocket doesn’t offer that), but don’t enable Lazy Load Images since that’s offered by WP Rocket.
In case you’re wondering: That “WordPress cron job functionality” error shows because I’ve replaced the default WordPress cron with a real cron job in cPanel.
That’s a wrap
Hope you found the guide useful and WP Rocket works great with SG Optimizer on your WordPress website!
