Several Cache Plugins at a Time

[ganapathy]

Our web developer is using three cache plugins (Smush, Asset cleanup and WP Fast) at a time to increase website page speed insights.

My questions:
Is this best practice?
Is there any dis-advantage?

Those are not all cache programs. They each do different things.

Smush resizes uploaded images.

Smush Image Optimization – Optimize Images | Compress & Lazy Load Images | Convert WebP | Image CDN

Optimize images & bulk compress images with lossless compression, lazy load, convert WebP, and properly size images via CDN for incredibly fast sites.

Asset Cleanup optimizes CSS and Javascript files.

Asset CleanUp: Page Speed Booster

Make your website load FASTER by stopping specific styles (.CSS) & scripts (.JS) from loading. It works best with a page caching plugin / service.

WP-Fast is an optimization and Security plugin which also allows easy setup of a CDN. It likely includes a cache; I've never used it.

WP-FAST | WordPress, Fast & Secure

Thanks @djbaxter . Always good answers & help from you.
Sorry, I wrongly mentioned "WP fast" instead of "WP Fastest Cache".

We are using these below two plugins also.
1.WP Fastest Cache
2.WP-Optimize - clean, compress, cache

You should disable any extra caches. You can still use plugins that have a cache and other features but just turn off the cache option.

When I had multiple caching enabled I had issues with live pages not reflecting changes even after purging cache. Now I just use one WP Plugin and a CDN. The site lost only a few points with speed.

I came across this today. I feel it's worth testing.

Sure. Will recommed to our web developer.

I have seen a menu collapse issue with live pages sometime. One of our websites is not reflected properly until we manually delete it ("Delete cache and Minified CSS/JS").
