Developing High Performance ASP. NET websites (1st) The following days I'm going to write a series of blog articles about developing high performance ASP. NET websites. Almost no clever or technically challenging concepts in these articles, because the premise behind the ideas presented in these posts are that t

Many of their applications are PHP wrote, why are they capable of running thousands or even tens of thousands of people at the same time?What about offline applications? Select Web servers with better performance Performance limit of a single Apache web server Choos

Many studies have shown that the most satisfactory time for users to open a webpage is less than 2 seconds. The longest waiting period that the user can endure, in the range of 6 ~ Between 8 seconds. That is to say, 8 seconds is a critical value. If your website is opened for more than 8 seconds, most visitors will eventually leave you. Google has performed a test. It takes 0.4 seconds to load 10 search results and 0.9 seconds to load 30 search results, as a result, Google's total traffic and

download, if required to provide, it is recommended to put large files on another server. 5use different hosts to divert the primary traffic to place files on different hosts and provide different images for users to download. For example, if you feel that the RSS files occupy a large amount of traffic, then use services such as FeedBurner or Feedsky to put the RSS output on other hosts, so that others access to the traffic pressure is mostly concentrated on FeedBurner host, RSS does not occu

The last time we used livejournal as an example, we analyzed in detail how a small website develops into a large-scale website performance optimization solution step by step to solve the performance problems caused by load growth in development, at the same time, these problems are fundamentally avoided or solved when designing the website architecture. Today, let's take a look at some of the common solutions for large-scale access and high load in we
