    @Strikerr Thanks. I think some times it selects a slower provider because there is not enough data. I am working to fix this. You can help btw https://github.com/jsdelivr/jsdelivr#performance-data-contribution

  • jimaekjimaek Member

    jsDelivr now has a new provider. CloudFlare joined our sponsors. If you guy have some time can you do some tests again? I am optimizing the algorithm as always.

    Also some cool graphs:
