Highest number of threads: Jmeter vs. WCat 6.3

Question

I want to use the highest possible number of threads on single computer.
I tried JMeter and for me it's not enough. I have only few computers to use.
Is WCat generating higher number of threads which I can reasonable simultaneously run than JMeter?

Answer 1

As mentioned above, you have at least a set of another options for your case, instead of wcat usage:

• using Jmeter:
  • try to apply resource reductions you can find at least in jmeter's wiki and best practices;
  • try Distributed Testing scenarios;
• Gatling
• Tsung

Answer 2

If by "threads" you actually mean concurrent users, Gatling could be a good choice. For example, I ran yesterday a test with 10,000 concurrent users and 1000 hits/sec (the application under test couldn't go higher).

Then, be aware that the load you'll be able to generate from a single server will depend on your use case. At some point, you might hit the NIC limit and then you'll have to scale out.

Answer 3

Are you sure the 2 tools can be compared : - can you do complex scripting with wcat ? - variabilize data ?

If you aim at simple hit/s then wcat or apache bench may be enough. If you are trying more complex scenarios then JMeter can run high number of threads provided you follow best practices.
