siege load test

Build an LVS load balancing test environment There are many ways to achieve Server Load balancer: local tyrants directly F5, the best performance, the most expensive If you have no money, you can use Apache. Nginx works on the fourth layer of the network. Although its performance is normal, it is flexible. For example, you can map port 80 to port 8080 of The Real

Because MySQLCluster implements automatic data synchronization and other functions, a layer of Amoeba serves only to share the load of the SQL layer, therefore, it is necessary for Amoeba based on the traditional single point MySQL service to help us do something. We will not repeat the environment building process. We will start two independent Because MySQL Cluster itself implements automatic data synchronization and other functions, the installatio

Everyone should have heard, Nodejs superior performance, concurrency is also very good, then we use Apache AB to the empty framework of node test, and then to some of the site test, or less certain reference meaning.The Apache AB Test tool is an analog multi-threaded concurrent request that has n multiple requests sent to the server at the same time, and also mak

So I thought about it again and did a system load

The advantage of this feature is that between the database and the client, added a layer of virtual service layer, is called the scan IP and scan IP Listener, in the client only need to configure the scan IP TNS information, through the scan IP Listener, connected to the background cluster database.
