What is the role of the IIS application pool analysis software? There may be 100-300 Web sites on an IIS 6.0/7.0 server, and if there is a problem with the ASP design of one of the sites, the CPU will continue to occupy 100%, causing the other sites on the same server to not function properly or to slow access. If th

Therefore, add an index to the _ mydata_key table based on the field keywords: mysql> ALTER TABLE `_mydata_key` ADD INDEX ( `keywords` ) After this index is created, the CPU immediately drops down, at 50% ~ Between 70%. Call show prosslist again, and the SQL call of website A rarely appears in the result list. However, the host runs several Discuz Forum programs, and several tables o

However, the host runs several Discuz Forum programs, and several tables of the Discuz Forum also have this problem. As a result, the cpu usage was reduced again.
