People who have experience with FTP download files have experience, downloading a 100M file separately is much faster than downloading 100 1M files separately, this is because the download needs to resolve the domain name, establish a connection, such as the additional cost of time, so download 100 files will do 100 times this additional overhead. So it would be much faster to download the 100 files as a single file.Based on the above method, the HTML in the JS file can also do a similar process

runtime, including the number of calls, can help the programmer to analyze the program's running flow. Gprof implementation principle: By the time you compile and link the program (using -pg compile and Link options), GCC adds the name Mcount (or "_ in each function of the application) Mcount ", or" __mcount ", a function that relies on the compiler or the operating system, which means that every function in the application calls Mcount, and Mcount
