Why is the download speed of comet bite so slow?

If you use the new version of BitComet, don't check the anti-bloodsucking protection, because once this function is turned on, you won't be able to connect a large number of users who downloaded with Thunder and Aauto Quicker. You should know that many of these users have large water pipes. If it's completely blocked, where's the speed? If you can only connect BC, BS or UT, you can only follow BT***, which means you can download resources only if you are lucky.
