Abstract:During normal development, you may encounter bottlenecks in various aspects of development, such as performance and system. Have you summarized them? Let's take a look at the classification of these system bottlenecks in this article!
In Zen and the art of scaling-A koan and epigram approach, RussellSullivan makes a very interesting conclusion: 20 traditional system bottlenecks are
used for publishing the web, which is generally 80, in this way, Wingate opens an HTTP proxy service with port 80.2. Go to the bindings page and select allow connections coming in on any Internet connections as the first option.3. On the non-proxy requests page, reject request is selected by default and changed to pipe request through to predetermined.

In Zen and the art of scaling-A koan and epigram approach, RussellSullivan makes a very interesting conclusion: 20 traditional system bottlenecks are common in software development. It sounds like there are 20 plots and it depends on how you plan these stories, it may be
the Hungarian naming method, which will be followed by the above Code style as much as possible in the subsequent examples. In other words, not all readers are required to abide by the rules, but readers are expected to follow the rules as a modern software developer.
The Hungarian naming method identifies the scope and type of the variable by adding the symbol of the corresponding lowercase letter before the variable name as the prefix. These symbol
