RE: Is it good practice to exclude common page items during record?
Yes, as Felix mentioned, it is good practice.
Idea is static content would be cached by browsers generally, so would be downloaded only once. If you run them thru JMeter (without caching enabled), JMeter would fetch them every time overloading the network. This is not a normal use case scenario, so it's better to remove static content like images, css, java script, etc from your samplers.

Generally, it is good practice. Probably, the checkbox "retrieve
embedded contents" in the HTTP sampler will do what you want. Only keep
recorded samplers for actual HTTP content (be it php, aspx or whatever)
and have Jmeter deal with the images.

Posted by Adrian Speteanu <as...@gmail.com>.
the cache manager is ok in order to simulate accurately. however downloading
the resources of a web page requires more things to download and therefore
more bandwith. it is more realistic, but the container of the web
application does the task of providing the resources and thus it cannot be
optimized through programming of the application at test (in my opinion, I
hope I'm not mistaking this)... so although it's realistic, it gives little
extra in load testing. in a browser however the sequence in which resources
are loaded may affect the rendering time of the web page (and for that you
can use tools such as firebug and yslow in order to evaluate the web page
and it's performance).

Re: Is it good practice to exclude common page items during record?
Posted by Sudip Kumar Bhattacharya <sk...@gmail.com>.
Yes. What I meant was either
Enable caching in jmeter
Or
Remove static images/css/js/etc
To get the realistic results
Caching manager wud give realistic results, but in most load tests your focus is on the response time against load on the dynamic resources. Static items just increase your data which u need to go thru then to create ur reports, thereby causing confusion

If this is significant for your application then you must also simulate the
way the browser requests resources and the number of requests it makes in
parallel. Also it depends on what your goal is. If it is whats the response
time under load you are better off calculating the static resource times on
a browser and adding it with safety margins to your Jmeter results (which
have static excluded).
>So you shouldn't just disable resources load.
I'd say this is my rule of thumb. I disable it unless I know of some reason
not too. Generated images do not fall under this category- i'm assuming the
original poster meant static css/js/images. Usually sites with high
performance requirements have a separate CDN so the static resource load
does not affect the page load.

I disagree. Depending on server application some resources maybe generated
and come cacheable. So you shouldn't just disable resources load.
JMeter HAS item to simulate browser's cache behavior. It's Cache Manager.
