Solution for Technorati being blocked and slow login to Wordpress admin pages, speed optimization

Recently, Technorati has been inaccessible. Originally, the Dashboard in the Wordpress backend provided users with a real-time link update service. Each time you logged in, the php page would send a cosmos request to Technorati via RSS to download the latest Technorati Links, thereby informing the WP administrator of the newest incoming link information. This was originally a very good added-value service, but... due to various reasons, when Technorati is inaccessible, you can only wait for the server-side TCP connection to timeout before you can enter the management page. Sometimes, the waiting might even drive you crazy. Here, we offer solutions for the issue where Technorati is blocked and the Wordpress management page login becomes slow, along with optimization tips to speed it up.
