Very Slow R2 performance in ASEAN

Hello, I have a tube website and chose Eastern North America as the location hint. In recent days, my visitors from ASEAN have complained that my videos are very slow to load; it takes them 4-20 minutes to play a video. Is there a solution for this? Oh, by the way, I haven’t enabled caching on Cloudflare because all my files range from 700 MB to 1 TB in size.
