4x banwidth usage, requests and LCP with cloudflare

Hello, I recently updated YASR plugin from an older version (about 2 years ago) to the latest 3.3.7 and then 3.3.8.

After a long search I found out that this plugin is the cause of a weird behaviour that I can see on my cloudflare.

When the plugin is enabled, cloudflare registers 4x times the bandwidth and 2-3x time the requests. All these requests are coming from Germany that is the area where the server is located, so it looks like that the plugin is making some calls back to itself, and the answers (fortunately, otherwise I would run out of bandhwidth limits) are given from cloudflare because it’s all cached traffic.

Not just that: when the plugin is enabled, LCP metric is getting bad, and I can also measure it in a longer request time:

I already enabled and disabled the plugin multiple times to compare so I’m sure that it is the cause, but I can’t find any more detail. No issues with the old version (2.x)

This is what I checked out:
– on my hosting server there are no additional requests nor bandwidth used, so it looks like the plugin is calling something that is already cached and cloudflare answers directly.
– because of this, on the raw access log on my server there are no logs about these requests so I can’t find further details.
– cloudflare doesn’t let me see a raw access log (only available to entreprise plans) so I can’t see there either.
– The problem is happening both with ajax option ON and OFF, no change at all. I don’t have cache plugins active.
– Tried both php7.4 and php8.0, no changes.

Any hint to understand what’s happening?

thanks, regards
