Someone needs to write a "LR Correlation for Dummies" I see serious demand for that sort of book. Don't know if how will HP react to that but just a thought.

Excellent thread btw. Compliments to the originator and other posters who provided the info.

Uh - see my comment in the chit-chat thread. There IS a "[LR] correlation for dummies" (correlation is required for all similar tools, not just LR) --- it is called the training materials! Correlation forms a significant part of the standard LR training course (not suprisingly.)

And, by the way, in regards to writing an "outside" publication, it would be almost impossible to create without infringing HP's copyrights, which have been fiercly defended ever since the Mercury Interactive days. Several people in this forum have tried to pursue avenues with first Mercury, then HP, to get permission to publish 3rd-party material, but it has always been stonewalled.

I agree.

Yeah that's what I figured. It's just that it gets frustrating with all the red tape and run around they give to go to another source...

OK, I have been in the Load & Performance Testing field since the mid 80's. I am on a new contract and having to lead the leaders on some performance testing issues. I am getting pushback right now on the number of VUsers the project wants to test to. Some thought process they are trying to venture down is, "why don't we just increase the amount of data each VUser puts into the system?" so they can reduce the number of VUser licenses. I once read a document that was very good at discussing and explaining the differences and plus/minus of number of users versus how much to throw at the system. The only thing that this feeble old brain of mine can honestly recall from that was that you really need to know some key timing information to truely get any information worth it. Since I can not find that document and am having a tough time articulating this whole concept to them, can anybody provide a link(s) to some info that would help?

On another side of this whole discussion was "Why do we need 1500 unique login ID's instead of having multiple concurrent sessions under the same ID?". I shudder at the thought of that one. I asked my boss if he thought our system could handle it if everybody on one floor of the building logged in under a single ID. To me, it screams potential contention and security issues.

This is all basic stuff and I have not had to "manage" the management through these issues in to many moons and would like some pointers to documnets/links I can pull from.

Thanks in advance,

Tom

Tom,
Try googling "performance test professional"
Theres a couple of articles on there...

I'm definitely in the 1 user id per concurrent user camp

Why? Contention, security (as you said) and caching

Yes it might be expensive, but it's a known cost... Unlike trying to fix ghost performance issues that not providing the correct data will undoubtedly throw up

Remember loadrunner is just a tool, if you don't understand performance testing , it's like trying to cut a piece of wood with a screwdriver... Maybe you can do it, but the results will be meaningless
