For our sample application, we implemented HTTP Keepalive in the TCAP interface to significantly improve performance.

对于我们的样例应用程序，我们在TCAP接口中实现HTTP Keepalive来大幅提高性能。

KeepAlive 5 at the global level of httpd.conf allows the server to handle 5 requests on a connection before forcing the connection closed.

conf全局级的KeepAlive 5允许服务器在连接强制关闭之前处理一个连接上的5个请求。

HTTP Keepalive solves this performance problem by considerably reducing the overhead associated with establishing and tearing down TCP connections.

HTTP Keepalive通过大幅减少建立和终止TCP连接的相关开销来解决这个性能问题。
