Ah… ya. Shouldn’t be an issue. Although you may still want to give its Guest Page Caching a whirl just to compare. Being able to place your sites cache physically closer to the end user will normally be faster than a cache that exists on your origin server.
For example, say I’m a user in London and your servers are in Dallas… If the network traffic only needs to go as far as Cloudflare’s closest data center (in London) rather than traversing the ocean back to Dallas to fetch the cache, normally the close one is going to be significantly faster.
