I have a web Service request that push a notification in a screen,I want to measure the time taken to display the notification in the screen after the request of the web service requested,so I want to send both requests in parallel. How can i do that ?

The two highlighted steps not occurred concurrently.
JMeter provides Synchronizing Timer which allows grouping requests so they could be executed at exactly in the same moment. Just add a Synchronizing Timer to your test plan and make sure that
it is at the same level with both requests
number of virtual users in Thread Group is >= what is set in the Synchronizing Timer
See Using the JMeter Synchronizing Timer for more information on running specific requests at the same time in your JMeter test.
You can use this plugin Parallel Controller that you can install with jmeter-plugins manager
You use Parallel Controller:

Can someone please explain the "Limit max thread number" property for the bzm parallel controller plugin? When monitoring requests from the browser we can see there are some requests that happen in parallel. Is this property to be set to the number of requests observed occurring in parallel?
What would be the issue of not setting a limit, if the scenario is run as part of an Azure pipeline? Would it automatically determine the max number of requests that are to be executed in parallel?
Thank you.
Parallel Controller executes all it's children in parallel.
The limit is introduced to support browser-like behaviour, the majority of modern browsers open up to 6 connections to a server in order to download embedded resources and execute AJAX calls.
So if you want your JMeter test to behave more like a real browser and you're using Parallel Controller to mimic calls to embedded resources or AJAX requests you should set the limit to match the browser you're trying to simulate
preparing test plan to send multiple http request. However, jmeter waits to send another batch of request till it gets response from first batch.
I want to send 10 concurrent requests per sec. If i run 1 mins, i should have 600 requests in the then. However, since jmeter waits to send another 10 concurrent requests till it gets response from previous 10 requests, I can't send 10 concurrent requests.
any pointer would be appreciated.
The easiest option is to go for Concurrency Thread Group which tries to maintain the defined concurrency level by kicking off new threads if current amount is not enough to conduct the required throughput. So basically you need to install Concurrency Thread Group via JMeter Plugins Manager and migrate your Sampler(s) there.

I have an Application where i have to do load test.Its like i have request A and B,and i have to test with 10 users and request should go like first request - A,B ,second request - A,B with ramp up period 0.
Could Any one help on this.I tried doing with Simple controller but the request are sent randomly and fring error
Check the box for "Run Thread Groups Consecutively" in your test plan. It will send your request A and B for first users then for second users and so on.
See this:
If you really need to wait until 1st user is done before starting 2nd one the fastest and the easiest solution would be setting Number of Threads to 1 and loop requests A and B 10 times in your Thread Group configuration.
If for any reason you need to have 10 concurrent users but executing requests sequentially you can go for Inter-Thread Communication JMeter Plugin which allows synchronizing JMeter threads (even residing in different Thread Groups)
The recommended way of installing JMeter Plugins and keeping them up-to-date is using JMeter Plugins Manager
My application is live application & three is a heavy use of AAJX call and Java scripts.
Successful login required three steps
Login validation
On login page browser post user login information and backed first validate it and set cookies & session id for further use.
After successfully validation of user information browser initiate two request parallel towards back-end.
Browser post a request to server & server send some XML data in every 10 seconds towards browser. Back-end push information in every 10 seconds up to user logged in.
Also browser post a ping request to server to make sure user is available and active.
To test the performance of UI by JMeter I am planning to create following test plan.
Test Plan
Main Login Thread
Ping Thread
Application Thread
Now I want to run thread 2 & 3 parallel after completion of first thread.
Please let me know if this is possible in JMeter if Yes how I can run two threads parallel after completion of first.
It isn't something which is provided in JMeter out-of-the-box as currently there is no way to jump over the number of threads which are defined on Thread Group level so you'll need to do some coding in order to work it around, i.e.:
Use JSR223 Sampler (or PostProcessor)
Develop custom sampler i.e. basing on ExampleSampler which spawns more threads in order to simulate AJAX parallel calls
See How to Load Test AJAX/XHR Enabled Sites With JMeter article for more details and some reference implementation examples.
i have one thread group in jmeter and in it i create several http request sampler and when i run this thread group,i found that seems all these http request executed one by one from "view rults tree". So i what to know how can all these http request run concurrently?
My thread group and test plan only need to be executed once one minute,and i use a bat file to run ,command is :
call C:\apachejmeter\bin\jmeter.bat -n -t C:\apachejmeter\app1.jmx -l d:\restmon\restmon.jtl
your prompt reply would be deeply appreciated!!!!!
This is how JMeter works:
JMeter creates threads defined in Thread Group
Threads start executing samplers upside down (default) or according to logic controllers
When there are no samplers to execute and no loops to iterate thread is being shut down
There are several ways to control concurrency:
Playing with ramp-up and run time
Using Synchronizing Timer which is capable of pausing threads until required number is reached and releases them at the same moment of time
Switching to Ultimate Thread Group which provides some extra options to control the load scenario.
I think that Synchronizing Timer is what you're looking for.
