In JS, most of the function calls are triggered by the user's active invocation, but in some events, such as MouseMove, Window.onresize, Touchmove, the number of calls to the function is very frequent, which consumes a large amount of memory space in the browser. Causes the browser to lag or even feign animation question. So the purpose of the function throttling is to reduce the number of calls to the function in these events, which is never controllable.There are many ways to implement a funct
information in the test-S (random number Seed)Used to specify the seed value of the pseudo-random number generator, and if the seed is the same, the sequence of events produced by the two monkey tests is the same. Example:Monkey test 1:adb Shell monkey-p com.shjt.map–s 10 100Monkey test 2:adb Shell monkey-p com.shjt.map–s 10 100--throttle Used to specify the delay between user actions (that is, the event), in milliseconds, and if this parameter is no
In fact, the earliest look at the design pattern is the simple understanding of the JS language itself, so it is easy to forget after reading the understanding, perhaps after the actual work needs to remember it;Look below: "en">"UTF-8"> "Viewport"Content="Width=device-width, initial-scale=1.0"> "x-ua-compatible"Content="Ie=edge"> In this case, the browser will probably check the window changes about 10 times per second, obviously bad for performance;Let's look at a throttling function to do the
a certain amount of time. For example, the blink of a person's eyes, is a certain time blink once. This is the most vivid explanation of function throttling.? function Stabilization refers to the frequent triggering of cases where there is only enough idle time to execute the code once. For example, in the life of the bus, is a certain period of time, if someone has to swipe in the car, the driver will not drive. The driver only drives when someone else doesn't have a credit card.Second, functi
event requests based on the time period. Consider the following throttle function:
Function Throttle (FN, interval) {
var doing = false;
return function () {
if (doing) {return
;
}
doing = true;
Fn.apply (this, arguments);
settimeout (function () {
doing = false;
}, Interval);
}
Window.onresize = throttle

Higher-order functions can be understood as functions above functions , which are commonly used, such as commonvar getData = function (URL, callback) { $.get (URL, function (data) { callback (data); });}Or you can use it in many closed scenarios.such as the anti-shake function (

The following articles mainly describe the Distributed Management of DB2 9. In this column, we will explain the actual operation steps for performing automatic maintenance, it also describes how to use the utility to throttle if maintenance operations need to be performed when the DB2 database is processing the workload.
Preface
The adaptive utility of DB2 9's throttling system enables maintenance during busy hours.

9.4. softnet_data StructureWe will see in Chapter 10 that each CPU has its own queue for incoming frames. because each CPU has its own data structure to manage ingress and egress traffic, there is no need for any locking among different CPUs. the data structure for this queue,Softnet_data, Is defined inInclude/Linux/netdevice. hAs follows:struct softnet_data{ int throttle; int cng_level; int avg_blog; struc
the probability of a touch event and a track event is 50% and 40%, respectively. A total of 200 tests are performed, as shown in Figure 3.12 and figure 3.13. You can use "-- throttle" to specify the interval between events to delay the occurrence of events. As shown in Figure 3.14, the probability of a specified navigation event is 80%. Each event occurs within one second, A total of 200 tests were performed. See Figure 3.15.

Strict mode requires the client to send the Accept header instead of the version specified in the configuration file by default, which means you cannot browse the API through a Web browser.
If the Strict mode is enabled and an invalid Accept header is used, the API throws a Symfony \ Component \ HttpK
