Load Testing SAP ECC

Hi ALL,

 

What is the best way to load test 1000 concurrent users for SAP ECC, we have 2 load generators 16 GB RAm each and controller 32 GB Ram, but when we try to run the scenario, beyond 300 users test fails as the RAM is fully occupied due to the fact that SAP ECC runs as a system process and utilizationis at peak.

 

Would need advise on how to proceed , as installing additional on premise load geneerators might not be the only option .

our license is on premise and not cloud based

Re: Load Testing SAP ECC

Great! You're finding out you have to adjust the load which the load generators have to supply have to match and not exceed the capacity your load generators can supply. At least as long as the objective is to get answers about the product (system under test) and not about your test equipment.

What can you do?

You can add more hardware, i.e., more load generators and keep the target of the number of virtual users and the work load per virtual user on the load generator the same.

You can keep the hardware the same and lower the target of how many virtual users you need while keeping the work load (the scripts) the same.

You can keep the hardware as now and the number of virtual users as now but making the scripts less taxing on the load generators.

Or you can change several factors at once (but I strongly adivce you to change one thing at a time between measurements - so this would be a multi phased approach).

Again, congratulations for actually noticing your bottle neck is NOT your system under test but your test equipment. That's a important finding!
