Is Jmeter Scalable?
Hi,
Im looking to delve further into jmeter and use it as the standard tool
I use for all of my clients that require performance testing. Ive
started looking at running jmeter via cloud injectors so I can get some
pretty decent load, but I want to understand how scalable it is.
Has anyone had any experience at running Jmeter, either via cload
injectors or just from a big server for say 6000+ concurrent users? did
it perform well, were the results accurate?
I hope im not being too vague!

Hi,
6000 users is easy to do.
For insanely larger tests (how about 1 million calls per second?), you
might find that other tools scale better. But only slightly, the difference
is given maybe not by the tool itself, as it is given by the technology
behind it. And those tools that I know of and seen in use, they aren't as
extensible as JMeter. As it uses Java and there are so many systems
working on Java, you can imagine its pretty performant.
Mind you that all large tests come with quirks. So do the tools you use, no
matter which they are. If your approach is correct, JMeter will scale both
vertically and horizontally... You don't really need clouding services to
do it if you have the patience to take the hard approach, but if you don't
have much time at your disposal, they might prove useful.
Regards,
Adrian Speteanu

Thanks Guys,
So are we safe to assume that scaling up jmeter tests will give us
accurate results, and we will not actually end up testing the jvm that
jmeter runs on?

Hello,
Yes it is scalable provided you use it well as any other performance tool.
We use it in our Test Campaigns and reach frequently 6000 VUs (distributed
testing) without reaching limits on Injector machines.
Performances are getting better and better with each new version.

In a word, yes. There's lots of approaches you can take (commercial, open source, roll your own) but the concept is well proven. I routinely run tests at higher volumes than you mention with no problems. My personal approach is to run lots of jmeter processes as isolated silos and group the results later - this is logically very scalable. But there's been significant work lately on making the Distributed Mode more efficient so you may have success there.
In industry terms I personally know of several high profile companies that use JMeter as their standard tool and there is also a video kicking around where Google talk about how they use it for their load testing. In each case they opted to build their own framework; it's not really that hard and the cost savings are stupendous.

There are businesses like Blazemeter who scale JMeter on their cloud
infrastructure. Look for technical details there for metrics and scaling
tips to avoid memory issues.
