Case phenomenon:When the pressure test, found a request pressure 80tps, the CPU occupied is very high (24-core machine, each CPU occupation rate of the total soared to more than 80%), and set the checkpoint did not have any error.1. The top command is as follows:2, understand the background to implement the logic: The general is such: after the server received the request, will be another KV server request data, take back the data, according to the us

In the development of applications under Windows, often need to use the timing, especially in some of the more time-demanding programs, the accuracy of the timing is very important, this article introduces two precise timing methods, the accuracy of the timing can be achieved MS level, and can be considered to be accurate, Can be used as a benchmark for time in most cases. Using API functions:: timeGetTime () to get the number of MS from the boot to the current, its return type is a DWORD type,

With the further construction of China's information network, the further improvement of network quality, high-speed, high-performance Ethernet switch will become the mainstream of network product development. The switch is an essential equipment for the network of large and medium sized enterprises, it plays a very important role in the network construction, it can increase the network capacity and improv

Implement a high-performance web crawler from scratch (I) network request analysis and code implementation, high-performance Web CrawlerSummary The first tutorial on implementing a high-performance web crawler series from scratch will be a series of articles on url deduplication, anti-crawler, how to improve crawling efficiency, and distributed crawler series.I w

High-performance communication library-zeroMQ, high-performance communication-zeromq First, let me introduce ZMQ (full name: ZeroMQ ): Official: "ZMQ (ZMQ for short) is a simple and easy-to-use transmission layer, a socket library like a framework. It makes Socket programming simpler, more concise, and more efficient. Is a message processing queue library that can be elastically scaled between multiple thre

PHP solves the problems of high website traffic and high concurrency. First, check whether the server hardware is sufficient to support the current traffic. A common P4 server generally supports up to 0.1 million independent IP addresses per day. if the traffic is higher than this, you must first check whether the server hardware is sufficient to support the current traffic. Common P4 servers generally sup

This article describes how to implement high-performance and high-concurrency counters in MySQL. counters in this article refer to the number of clicks, preferences, and browsing times in this article, you can refer to many projects and implement counters as needed. for example, you can design a data table in this way when clicking through a website article, for example, "article_id, article_name, article_c

Build a high-availability and high-concurrency wcf cluster using nginx, nginxwcf In many cases, zookeeper is the preferred choice for Complex Balance Based on wcf, which can have better control granularity. However, zk is not very friendly to C # And is relatively difficult to implement. In actual situations, if If your load mechanism is coarse-grained, nginx can be used first to achieve complex balancing

Implement High-performance and high-concurrency counters in MySQL (such as the number of clicks in articles) and mysql counters There are a lot of projects that implement counters at will. For example, when we implement the number of clicks on a website article, we design data tables like: "article_id, article_name, article_content, article_author, article_view ...... Record the page views of this article i

With the website's business more and more, the service of the website becomes very important, suppose one day your server hangs, will be a big disaster? And this kind of thing happen the probability is not small, power off, server hard disk bad, memory bad and so on, will make your system hangs, and high concurrent access sometimes will make system resources exhausted, and then lead to server outage, then the solution, that is the cluster, Put the sam

difference between inferior SQL statements and high-quality SQL statements can reach hundreds of times. it can be seen that a system can not simply implement its functions, instead, we need to write high-quality SQL statements to improve system availability. In most cases, Oracle uses indexes to Traverse tables faster. The Optimizer improves performance based on the defined indexes. However, if the SQL cod

1. HTML staticAs we all know, the most efficient and least consumed HTML pages are purely static html pages, so we try our best to make the pages on our website adopt static pages, this simplest method is actually the most effective method. However, for websites with a large amount of content and frequent updates, we cannot manually implement them all, so we have a common information publishing system CMS, news channels such as the portals we often visit, and even other channels, are managed and

Big integer BIGN Design and Implementation of C ++ high-precision templates, bign high-precision First of all, I would like to thank Liu rujia for his book "algorithm competition getting started classic". As we all know, the unsigned long with the largest storage capacity in C ++ also has an upper limit. If we want to calculate a very large integer, we will be overwhelmed, I wrote a
