1. Low code efficiency-(take post. cgi in a famous Chinese forum as an example to obtain the code of the next thread)
I have no intention of attack, and I do not know whether this code is still available. This is the May 2001 version.
 
I will only comment on this clip
$ Dirtoopen = "$ lbdir". "forum $ inforum"; // open the Directory of the forum
Opendir (DIR, "$ dirtoopen ");
@ Dirdata = readdir (DIR); // read all files
Closedir (DIR); // Close the directory handle
@ Sorteddirdata = grep (/. thd. cgi $/, @ dirdata); // Obtain all topic files
@ Newdirdata = sort numerically (@ sorteddirdata); // sort
@ Neworderdirdata = reverse (@ newdirdata); // reverse
$ Highest = $ neworderdirdata [0]; // Retrieve the file name of the largest digit
$ Highest = ~ S/. thd. cgi $ //; // obtain the largest number
$ Newthreadnumber = $ highest + 1; // add 1 to obtain the expected digital data
As you can see, when posting a new topic, the code is very short, but all the files in the entire forum directory are scanned.
Sort once and twice
Assuming that this directory has multiple NN topics, the speed can be imagined.
Therefore, the "Forum seems to be slow, because there are many JS resources"
Argument
Is it true?
2. The code is nonstandard and belongs to the workshop type.
For example, in a famous CGI forum in China, the program component name is inexplicable, bbs, bbs1, bbs2,
Cjyh, xiu, and yhreg,
Worse, it usually appears inside the Chinese program.
