How can I test my upload speed with and without Cloudflare WARP?

You can test your upload speed by using reputable speed test websites or applications like Speedtest.net, Fast.com, or Ookla Speedtest. First, disable WARP and run a test. Then, enable WARP and run another test from a similar server location to compare the results. Ensure you are testing from the same network environment for accurate comparisons.
