How to solve the Capmonster proxy perfectly？

[jsyz0055]

I added 1500 IPv6 IPs to CAPMONSTER. At the beginning of the beginning, the verification code was very fast. Capmonster kept a low thread and the success rate was very high. However, after it was used for many days, the CAPMONSTER thread became more and more and more and more High, the verification speed is getting slower and slower, and the success rate is slowly decreasing. Whether it is a rotating agent or restarting agent, the effect seems to be bad. Except for changing a new agent, is there a good way to solve this problem? Or a good Japanese agent website can be recommended. Thank you!
