Although the block size of any pair of adjacent layers in the hierarchy is fixed, other levels can have different block sizes.

To analyze the largest source IP address and address, we need to execute two commands. The first command is to read the user from the log and write it into the XML file, the second command is to read the XML file and render it as a graph! Run the first command to write data to the XML file: "C: \ Program Files (x86) \ log parser 2.2 \ logparser.exe" "select top 10 extract_prefix (Remote-endpoint, 0, ':') as remotesendinghost, count (*) as hits int

three aspects one by one will greatly help improve the website's performance. Database performance optimization I,Field Creation 1. reduce cross-table queries After the requirements are determined, databases are often created. Therefore, database creation and database operations are inseparable from the addition, deletion, modification, and query operations. Queries should be frequent operations, A basic principle for improving query operations is to
