Since ASP.net, developers have been asking for a solution, and ASP.net 2.0 uses precompilation to provide an effective solution. Pre-compiling options When the application is first started, ASP. NET dynamically analyzes and compiles all the asp.net files (aspx pages). The running environment buffers the results of the compilation to better serve all future requests. Starting an application for the first time after a server reboot or a Web server reboot means that the process will start again.

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.

When your users complain that the changed information does not change, the deleted data is still displayed, you pinch the count, it is estimated that the database master never synchronized.As with other databases that provide data synchronization, MongoDB also encounters synchronization latency issues in MongoDB's replicaOr provideserythromycin stearate 500mglike though.

Solution to ssh connection latency-Linux Enterprise Application-Linux server application information. The following is a detailed description. Generally, the ssh connection latency is caused by reverse DNS resolution enabled by sshd by default. Modify/etc/ssh/sshd_config of the ssh server and change UseDNS yes to UseDNS no. However, we have encountered Anonomous Ubuntu, and there is still a

Latency function error: volatile and volatile An inexplicable error. Latency caused by the use of javasick. The initialization is like this: // SysTick Configuration SysTick_CLKSourceConfig (SysTick_CLKSource_HCLK_Div8 ); If (SysTick_Config (SystemCoreClock/1000) // enable clock interruption and configure Clock. { While (1 ); } Then: // Latency function. 1 nTime

Android Activity latency jump, androidactivity Sometimes we find that some APP boot pages are waiting for a while to be transferred to the Home Page. In fact, they are processing data operations at this time. Today we will simulate the Android Activity delay jump function! In fact, it is very simple to add a piece of code: New Handler (). postDelayed (new Runnable () {public void run () {// code of the place you want to jump to finish () ;}, 2000)

synchronization mechanism relies on Slave to actively send requests to the Master to obtain data. In addition, due to server load loss and network congestion, the data synchronization latency between the Master and Slave is completely unguaranteed. Within 1 second, it may take several seconds, dozens of seconds, or even longer. Due to data delay, when the application updates data on the Master and needs to read data from the database immediately, at

It's a bit like a queue on steroids (but quite a lot of steroids) and are one of the key innovations used to make the LMAX Exchange run so fast. There is a rapidly growing set of information on what t

1. Select the correct languageScripting languages can't be used, although they can run faster and faster, and when you're looking for a few milliseconds of delay you can't afford to explain the language, you want to have a powerful memory model that can be programmed without lock, with Java Scala and C 11 or go in the language of choice.2. Put everything in memoryI/O kills your latency and ensures that all your data is in memory, which means you manag

Article Title: how to solve the login latency of SSH connections in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

There is a good Test on the Performance of WCF in CodePlex, WCF Latency Test Harness, different binding (netNamedPipe, netTcp, netMsmq, basicHttp, wsHttp, Remoting), different serialization methods, different request data volumes, different request methods for testing, the test content can be set through the configuration file. The test metric is latency. There is A throughput test on MSDN: A Performance Co

In the morning, there was a piece of translated news in the news of major open-source websites-"Sun engineers were surprised to find that roar could increase the hard disk latency." Another YouTube video, Brendan Gregg, an engineer at the fishworks lab, yelled at the array and observed significant latency on a computer's monitoring software. There are a lot of comments about this news, and many people thi

JQuery latency plug-in doTimeout, jquerydotimeoutIn many specific applications, the event delay trigger is required. The setTimeout function is used in specific implementation, but it is still inconvenient to use. So here we introduce a jQuery plug-in doTimeout, this plug-in can achieve the same effect as setTimeout, and is easy to use. At the same time, you can forcibly execute the callback function before running timeout. Supports jQuery chained cal

Use zabbix to monitor latency of international linesIn many cases, the lines of various manufacturers in China are unstable, but they can only be tested temporarily. No detailed statistics are provided. Here, zabbix is used to collect statistics under this record.Trigger can be used for alarm when you are concerned about latency1. Compile the zabbix monitoring script. The following uses monitoring the Hong Kong server as an example: #! /Bin/bash

In-depth analysis of network latency during Android boot In general, the property of phone is persistent to true, and the phone process is called up earlier. Applications modified by android: presistent will be started by AM after the system is started, even if they are not running, AM also calls startProcessLocked to start the process. Start package com. android. phone, that is, phone application. This will directly call onCreate () of PhoneApp and e

reuse of data. Reusing data while it is still in the cache avoids sustaining memory fetch stils and generally CES the memory bus load. Memory latency The times it takes to initiate a memory fetch is referred to as memory latency. During this time, the CPU is stalled. The latency penalty is on the order of 100 clock cycles. Caches were authorized Ted to hide suc

When FFMPEG was recently used for h264 encoding, it was found that the video encoding was delayed, rather than real-time Encoding. After some research, we found thatAvcodec_open2Function When encoder is enabled, SetAvdictionaryThe key code is as follows: Avcodec_open2 function: int avcodec_open2(AVCodecContext *avctx, const AVCodec *codec, AVDictionary **options); Solution: Avdictionary * Param = NULL; // h264, set to encode latency to encode imm
