Bad performance clients using IPv6

Hi!

We are experiencing very bad performance when accessing our site using IPv6, the site could take 30-40 seconds to load.

When using IPv4, the site loads in about 3 seconds.
Anyone else had this issue?

Best regards
Johan

Hi!
We found the error.

We have geolocation blocks in our firewall.
For some reason it triggered false positive when we used IPv6 addresses.

Nothing wrong with Cloudflare.
