Slower IPv6 speeds can occur due to several factors. Your ISP might not have fully optimized its IPv6 infrastructure, leading to routing inefficiencies. Distance to the nearest IPv6-enabled Cloudflare PoP (Point of Presence) can also play a role. Additionally, your home network equipment (router, modem) might not be fully optimized for IPv6, or there could be compatibility issues.
