Load Test with embedded resources chokes CPU
A load test with downloading just the HTML scales upto 300 users on one
Load generator (8 Core, 8 GB RAM - CPU at 20% max and Memory at 5%).
However, when a similar profile is tested with download of non-HTML
embedded resources (images, css, js, etc.,) along with HTML, the LG gets
utilized to the max (100% CPU, Memory still at 20%) with just 30 users.
Testing the same profiles with Load Runner, there is not much difference on
LG performance between the 2 profiles

Hi - I am Ganesh working with Bincy on the same issue addressed here. So,
just to add, we did try Blazemeter as well and the same behavior was
observed there with LG resources maxing out at 30 users when downloading
the non-HTML resources along with the page. Max Page size : 2 MB. TPS
targetted 4 to 6.

Re: Load Test with embedded resources chokes CPU
Posted by Ganesh Muralidhar <ga...@gmail.com>.
Now, I am quite curious to know what is the exact change in 3.3 that is so
resource effective :)
So, last time when we said we tested with 3.3, it was a miss from our side
in our custom shell script where we were still using 3.0. Now, i have
changed the version to actual 3.3 and tested. Seems like the CPU is much
stable compared to that of 3.0
Test on 3.0 - CPU choking to max 32 core (that is the max i have on my
machine)
Test on 3.3 - CPU stays below 2 core
Please do share the exact change that is implemented between 3.0 and 3.3

Re: Load Test with embedded resources chokes CPU
Posted by Ganesh Muralidhar <ga...@gmail.com>.
No sir.. my 30 users are not simultaneously run. They are concurrent. And
my response time is nothing less than 2 seconds with another 2 seconds of
think time added on top of it. So i wil never reach 600 MB. The max I can
reach is only 150MB that too in an ideal case.
Also not all 2MB is downloaded at the same moment as the concurrent calls
are only 6 for resources and the overall weight of all page resourcess
together is 2 MB.

RE: Load Test with embedded resources chokes CPU
Posted by rw...@gmail.com.
If your page has 2MB of data on it, and you are running 30 simultaneous users – that is 60MB per test of simultaneous data – which is roughly 600Mbits/sec – or 60% of your network’s bandwidth. That is substantial, and could account for your problem. There is no way you will get to 300 simultaneous users if you are downloading 2MB per user – and you only have a 1Gb network. Remember, network speeds are referenced in “bits per second”, and there are ~10 bits per Byte of data (there are 8-bits per byte, plus some overhead – so I usually round it to 10-bits per byte). So 2 mega “Bytes” is roughly 20 mega bits…

Our network switch is nothing less than 1GB and the testing is happening internal to the network. So no chance of network contention here.
Secondly, after updating the JMeter version to 3.3 the CPU contention seems not to be appearing again. Also, as Antonio mentioned, the below mentioned bug fix sorted this.

Keep in mind, images (especially) are a lot of bytes worth of data. If your HTML is 10K, but you download a relatively small banner image - that can be 100K of additional data (e.g., more than 10X the workload). Of course that’s a lot more work for the system. A typical web page will have 10-20KB of "skeleton" framework, but could have several megabytes of images and non-HTML files. A multimedia page could have several times more of that if you include streaming resources like movies or sounds.

Re: Load Test with embedded resources chokes CPU
Posted by Ganesh Muralidhar <ga...@gmail.com>.
Our network switch is nothing less than 1GB and the testing is happening
internal to the network. So no chance of network contention here.
Secondly, after updating the JMeter version to 3.3 the CPU contention seems
not to be appearing again. Also, as Antonio mentioned, the below mentioned
bug fix sorted this.

RE: Load Test with embedded resources chokes CPU
Posted by rw...@gmail.com.
Are you sure it's just CPU? It may be bandwidth for the network device that is constrained - and the CPU is trying to figure out where to put all the packets.
Keep in mind, images (especially) are a lot of bytes worth of data. If your HTML is 10K, but you download a relatively small banner image - that can be 100K of additional data (e.g., more than 10X the workload). Of course that’s a lot more work for the system. A typical web page will have 10-20KB of "skeleton" framework, but could have several megabytes of images and non-HTML files. A multimedia page could have several times more of that if you include streaming resources like movies or sounds.

What is the size of your JVM Heap ? If you didn't change it then it can
explain your issues.
Also why are you using an old version as 3.0, ? Last version is 3.3 ?

Hello,
What is your jmeter configuration ?
Did you change any setting ?
What is your jmeter version ?

Re: Load Test with embedded resources chokes CPU
Posted by "glinius@live.com" <gl...@live.com>.
Having a larger memory and CPU footprint for test configured to download
embedded resources is expected as in the majority of cases main request is
relatively small being compared to embedded resources size.
1. Make sure you're following JMeter Best Practices
<http://jmeter.apache.org/usermanual/best-practices.html>
2. Make sure you're using the latest version of JMeter
3. Make sure you have HTTP Cache Manager
<https://www.blazemeter.com/blog/using-http-cache-manager> added to your
Test Plan. This bit is vital as real browsers download embedded resources
found in the web pages (images, scripts, styles, fonts, etc.), but they do
it *only once*, on subsequent requests these embedded resources are being
returned from the browser's memory and/or disk cache. So having HTTP Cache
Manager is a must for properly simulating real users, otherwise you will be
conducting too much load therefore your test results won't be accurate.
