当表单数据有效时，表单数据实例排队并等待发送到服务器（当与服务器建立连接时）。
When the forms data is valid, the forms data instance is queued and waits to be sent to the server (when a connection to the server is made).
注意：如果创建新的代理超出了这一限制，那么连接会排队等待下一个可用的代理来服务请求。
Note: If creating a new agent exceeds this limit, then the connection is queued up and waits for the next available agent to service the request.
注意，一旦发送完所有排队等待的消息后，它将关闭连接。
Notice that once it has sent all of the queued up messages, it closes the connection.
调优连接池的目标是确保各线程都有一个数据库连接，并且请求不需要排队以等待访问数据库。
The goal of tuning the connection pool is to ensure that each thread that needs a connection to the database has one, and that requests are not queued up waiting to access the database.
超出此限制的连接需要排队，直到等待接受的连接数低于限制值。
Connections in excess of the limit are queued until a space below the limit becomes available.
