加速时间和同步计时器有什么区别 [英] What is the difference between Ramp up time and Synchronization timer
问题描述
示例:
`1.线程数= 100 加速时间= 20，表示每1秒= 5个请求将被处理. 循环计数= 1
`1. No of Threads = 100 Ramp-up time = 20, means every 1 second = 5 requests will be processed. Loop Count =1
- 同时: 如果我会像下面这样 线程数= 100 上升时间= 1 循环计数= 1`
- In the same time: If i will do like below No of Threads = 100 Ramp-up time = 1, Loop Count =1`
并将同步计时器":模拟用户数"归为组= 5. 同样在这种情况下，J计量器一次处理5个请求.
And put Synchronization Timer : No of Simulated user to group = 5. In this case as well, J meter process 5 requests at one time.
那么，以上两个概念之间的逻辑有何不同?
So what is the different logic between the above 2 concepts.
推荐答案
考虑情况1， 线程数= 100，启动时间= 20，循环计数= 1. 这意味着每1秒将引发5个线程. 根据响应所花费的时间，测试将运行至少20秒或更长时间.
Considering case 1 where the Number of threads = 100, Ramp-up time = 20 and loop count =1. This means that for every one sec 5 threads will be induced. Depending on the time taken for the response the test will run for at least 20 sec or more.
考虑情况2， 线程数= 100，加速= 1，循环计数= 1并且 将没有模拟用户的同步计时器添加到组= 5 将会一次添加5个用户批次.
Considering case 2 where the Number of threads = 100, Ramp-up=1, loop count=1 and Adding Synchronization Timer with No of Simulated user to group = 5 A batch of 5 users will be added at once.
两个测试都不需要花费相同的时间来完成.
Both the tests don't take the same amount of time to complete.
- 在情况1中，在1秒钟的时间内分配了5个用户.即每0.2秒增加一个用户.
- 在第2种情况下，一口气将5个用户添加到活动线程中.
要了解有关同步计时器
为了最好地理解这两种用例之间的区别，请将线程数增加到200，同时保持其余参数不变.这样就可以轻松注意到差异.
To best understand the difference between the 2 use cases, increase the number of threads to 200 while keeping the remaining parameters as is. Then the difference can be noticed easily.
