Web games, especially the instant combat webgame with multiple online users at the same time, performance optimization is an inevitable problem in the development process and in the later stages of development. After the hardships, we have summarized a Best Practice: latency strategy. To put it bluntly, just one sentence: Do not do too many things in one frame. Then, let's make a summary.Understanding asynchronous single thread of Flash Player First,

11.3.1.2 Haskell's latency calculation policy, 11.3.1.2haskell 11.3.1.2 Haskell latency calculation Policy In lazy evaluation strategy, the parameter value of the function is not calculated during function calling until it is used later. Let's go back to the previous example: TestAndCalculate (Calculate (10 )); Haskell jumps directly to the subject of the TestAndCalculate function. Haskell remembe

Js enables delayed loading of webpage images to increase webpage opening speed and js latency There are many ways to increase the speed of webpage loading, using jquery. lazyload. js achieves asynchronous and delayed loading of images. For websites with a large number of images on the page, it is a good way to increase the speed of webpage opening. On the left side of the bar page of the Code official website, you can see an article thumbnail display

Problem description: ProgramAfter the master database is updated, the data queried from the slave database does not change. It is suspected that the synchronization delay of the Master/Slave database is caused. Check the master-slave synchronization status from the database and find that seconds_behind_master takes more than one thousand seconds. Under normal circumstances, the latency of the Master/Slave database can be tolerated for more than 10 s

In the MySQL world, Haproxy is often used as a software load balancer. Peter Boros explains how to use the Percona xtradb cluster (PXC) to set it up in a previous message. So it only sends the query to the applicable node. The same method can be used for general master-slave settings to read the load and spread across multiple nodes. However, with MySQL replication, another factor starts to work: replication latency. In this case, the mentioned Percon

In addition there is a place to pay attention to, for scan words, a scan100, all our final statistics RPS is in the statistical number of good to 100 as the approximate RPS

external paging program FSBUF (used by the JFS2 file system). In addition, there are psbuf, which are fixed memory buffers used for I/O requests to paging space. In Figure 2, the vmstat-v command displays a value that is the average since bootstrap. Because the server may not reboot for a long time, be sure to take two snapshots in a few hours to check for changes in these values. Here, they grow fast and need to be tuned.

Label:In a MySQL replication environment, we usually only judge the latency of the slave based on the value of the seconds_behind_master . This is acceptable in most cases, but is not accurate enough and should be considered for more factors. First, let's look at the state of slave: [Email protected] [(none)]> show slave status\g *************************** 1.

Use native JS to encapsulate the Tap event to solve Ms latency on mobile terminals FastClick The existing plug-in fastclick can solve this problem, but it also has drawbacks: The latest version of the plug-in on GitHub is 25.4kb in size, lightweight as the trend, saving time. Its core idea is to cancel the default click Time and determine the type of the current dom node for corresponding operations. This judgment process is cumbersome. MyTapEvent I a

Spydroid-ipcamera This project can turn Android devices into a beautiful IP camera for webcams. Spydroid is a small app that can streams your phone's camera and microphone to your browser or VLC. It's the most powerful tool on the market and a way to transfer audio/video from your smartphone to your computer. With support for resolutions up to 1080p and running ICS or JB on your phone, you can support the AAC format. :http://www.devstore.cn/code/info/559.html source code runTurn Android into a

JavaScript: The Definitive Guide 5th: In practice, setTimeout tells the browser to enable the setTimeout Function after it completes execution of the event processor for any current delay event and updates the current state of the document. In fact, this is a technique for skipping the tasks to be executed from the queue. Back to the previous example, when the JavaScript engine executes onkeypress, because there is no multi-thread synchronous execution, it is impossible to simultaneously proc

This article mainly introduces jQuery's implementation of the drop-down list of two-level tab switching with latency. It involves the implementation techniques of jquery mouse events and dynamic conversion of page element styles, and has some reference value, for more information, see the following example. Share it with you for your reference. The details are as follows: This is a drop-down list menu with delayed effects based on jQuery, with animat

The command cycle is based on the machine cycle.

Latency loading of front-end images Images displayed in the visible area of the browser cannot be flushed out in time, so that images in the visible area can be immediately loaded in, the image that is not in the visible area and needs to be displayed by scrolling through the scroll bar will be displayed after the image is rolled to the visible area. I was planning to write a blog about the detailed technology of front-end image delayed loading yester
