engine that enables the enterprise network to have the ability to upgrade in the future, and the center switch of each level-2 unit uses Cisco's Catalyst 4006; the second-and third-level switches use the Cisco Catalyst 3500 series, mainly because of the high performance and stackable capabilities of the Catalyst 3500 series switches.At present, the three parts are connected to the Internet according to the
master database for the game. Besides, there are only a few administrators here, which cannot affect the performance of the game server.
Today, the project leader directs all the databases to the servers in the company. I copied a copy to the local machine to see what went wrong with the performance of the statistics platform.
