Remote server processing time doubled since switching to Cloudflare

Hi, we switched to Cloudflare a few weeks back but have since seen our site performance decrease with page load times doubling.

The screenshot shows the day that we switched, our server processing time doubled.

We’re using the default setup for Cloudflare, is there anything we’ve missed that we may need to turn on / configure to help get this back down?

Thanks,

Turn off the limit on the rate of connections allowed per IP.
That’s my solution for my website, not sure how yours is

Rate limiting not turned on currently, sadly.

That looks like you did not configure Cloudflare properly so cache requests. But without any domain/URL it’s hard to say anything, so please provide a domain and even better a specific URL this happens at.
