The reverse proxy can also provide load balancing for multiple servers in the backend, or provide buffering services for servers with slower back-end. In addition, the reverse proxy can enable advanced URL policies and management techniques so that Web pages that are in different Web server systems exist simultaneously in the same URL space.From a security standpoint: A forward proxy allows a client t

According to the current environment, there was a 6-fold gap in the test. Insert 500/5000/50000, respectively, The transaction is started in 480 ms/4546 ms/47407 ms respectively. When no transaction is started, the values are 3100 ms/30859 ms/308802 ms respectively. Why? After careful analysis, this should be related to sqlserver's back

for the production environment, fast running, slow startup speedThe JVM working in server mode can greatly improve performance, but the app's startup will be about 10% slower than client mode. When this parameter is not specified, the virtual machine initiates the detection of whether the host is a server, if it is, starts in server mode, or starts in client mod
