1. you do not have to fork each request once. Don't underestimate this fork. for a logic with a very large access volume, using CGI will cause a large number of processes in the system fork. If there are too many processes, the switchover may result in a high overhead.
2 FCGI initialization does not require every request. Sometimes your business logic needs to connect to a server to query data. if FCGI is used frequently, you can establish a persistent connection. If CGI is used, a certain number of TIME_WAIT connections are generated each time a connection is established, whether the connection is closed by the server or the CGI is closed.
FCGI disadvantages:
1. if there is a problem with your program implementation somewhere, such as a small memory leak, the memory occupied over time will be large, and CGI will not. To avoid such problems, many people prefer to exit automatically after FCGI processes a certain number of requests.
2 FCGI resident memory, which occupies the point memory space.
In short, it depends on the choice. if there is a large amount of access to a certain program, CGI can not support the service or the business logic requires resident memory services, use FCGI. otherwise, if you can use CGI, use CGI.
