I Have a Thread Group created in my Test Plan. I have set the Thread Group to run 20 Threads with Ramp Up Period as 0 and Loop Count as 1.
Now i have created 5 JDBC Sampler Request each which runs different queries against the same Database, so when i start the test , it should kick start 100 queries (20 * 5)
I also generated a Summary report and copied pasted parts of that report.
Sampler Label No of Requests per Sampler Average( in milliseconds)
------------- -------------------------- --------------------------
MYSQL JDBC Request 1 20 8571
MySQL JDBC Request 2 20 5154
MySQL JDBC Request 3 20 5927
MySQL JDBC Request 4 20 1290
MySQL JDBC Request 5 20 1449
TOTAL 100 4478
In the Summary Report taht i have compiled above, what does average of 4478 milliseconds mean?
Does this mean that it took 4478 milliseconds to run 20 threads on an average ? or does it mean that it took 4478 milliseconds to run 100 queries?..can someone help me here. I could not find this information anywhere in the Jmeter apache documentation.
Thanks in advance.
As per this documentation:
https://jmeter.apache.org/usermanual/component_reference.html#Summary_Report
Average : The average elapsed time of a set of results
So it means its it:
Sum of all request's response time / total number of requests

In my test plan I have 5 Thread groups with following number of users for 1HR,
Bulk Upload - 250 User
Log Analyzer - 50 User
Library - 10 User
CSV File Processer - 5 User
XLS File Processer - 5 User
For a particular execution I want to follow the following pattern,
Objective :
Want to execute this for 2HR (this is easy which I changed in the duration)
After every 20-30 min I want to increase the load to 10-20%
means after 30 min (example) the total user for Bulk Upload will became 275 User (if it is 10%) and similar for others and going to execute for 30 min.
And after 1HR of test Bulk Upload will became 302 User and similar for others and going to execute for 30 min.
Is there any way we can do this in JMeter in the same script during the execution.
you can achieve this by using a Ultimate thread group with the following settings.
The easiest is to just increase the total number of threads to 40-80% and amend the ramp-up period accordingly.
Alternatively you can consider using i.e. Concurrency Thread Group or Ultimate Thread Group where you can flexibly specify users arrival rate, something like:
These thread groups can be installed as a part of Custom Thread Groups bundle using JMeter Plugins Manager
I am doing performance testing using JMeter for a 365 dynamics ecommerce website. Script is written and its working fine for following flow: Homepage> category listing> product detail page> add to cart> and complete checkout.
I want to run my script for 200 concurrent users with some time interval. Like, start with 30 concurrent sessions for 10 minutes then increase 60 users with total concurrent session 90 for next 10 minutes. Then increase 44 users with total concurrent session 134 for next 10 minutes, Then increase 66 more users with total concurrent session 200 for next 10 minutes.
I am using ultimate thread group for this but not sure how to set configuration. See attached image.
I think you should amend your setup to introduce initial delay incrementing by 600 seconds for each group of new arrivals. The time to hold the load needs to be reduced by the same factor.
Example setup:

I need to perform the following scenario in JMeter:
Every 20 seconds a user will start pinging the server (will ping every 5 seconds)
1000 users.
So it start with one user that will ping every 5 seconds and after 20 sec another user will start pinging every 5 sec, and this will continue for 1000 users.
At the end 1000 users will ping together every 5 sec and all this need to run for 24 hours.
Define Thread Group with 1000 users,
Ramp Up Period 20000 - meaning every 20 seconds new users will start
Loop Count = 17280 (5 seconds per day count)
and add as a child to your ping request a Constant Timer with 5000 milliseconds
It will execute every 20 seconds a new user which will ping every 5 seconds. example in View Results Tree:
I am using Google Search Console URL Testing Tools API, I have a problem in the understanding limit quota of API. It says:
Project per-second limit per 100 seconds = 1
User per-second limit per 100 seconds per user = 1
What does that mean?
Most of highly used APIs (google, facebook..) have short-time limits and long-time limits for better control over traffic. It allows developers make many requests (eg. 20000 per day) but prevents throttling if someone would try to eg. send 1000 requests in one second, which could clog api endpoint.
What you have in your google console:
Project per-second limit per 100 seconds = 1
That means you can make 1 query for 100 seconds in each project.
And:
User per-second limit per 100 seconds per user = 1
That means you can make 1 query for 100 seconds for each user connected to project.
That two limit rules putted together dont make much sense beacuse second rule will never be triggered (both have 1 request per 100 seconds but first one is for 'higher' resource and will block more requests).
Example of many limits you can see eg. in Analytics API where we have:
Queries per day = 50000
Big limit for queries per day.
Queries per 100 seconds per user = 100
Small limit per 100 seconds and per user so they can prevent too high peaks of requests from single user.
Queries per 100 seconds = 2000
Medium limit per 100 seconds.
I am now doing load test about rethinkdb.
and found the same query's response become very slow when many same queries be send at one time.
■the info about test.
1)rethinkdb version 2.3.0
2)send query vie java driver
3)there are Several tens of thousand records in one table.
■this is the test result.
send query thread number：
1 2 3 4 5 6 7 8 9 10 15 20 30
query response time(ms) with send query thread number up.
466 701 964 1236 1475 1734 2009 2359 2531 2874 4234 5383 7848
■Question
query response time become longer and longer with sending query thread number up.
who can tall me why?
anything very be helpful thank you.
my English is poor. I am sorry if some English words are wrong.
Rethink java driver is synchronous. So, if you are using just basic driver without any additional pools of connections, your query will be sent only after completion of previous queries.
