Comment on LoadRunner vs. Performance Center by Plymouth Rock

From my viewpoint the only major differences between Performance Center (v9.5) and Loadrunner are:

1) Performance Center allows you to swap licenses across Controllers, while LoadRunner does not. Frankly, this is the only thing I think PC has going for it. A more elegant solution would have been to develop a license server for LR.

2) Performance Center must be installed on at least 2 extra boxes (analysis and web server, and a DB server) if you plan to use it with any sort of user base. LoadRunner can be installed by anyone familiar with LoadRunner anywhere.

3) Performance Center puts a web interface on top of the LoadRunner interface (so you have another layer of potential failures to diagnose).

4) Performance Center can act as respository for all scenarios, scripts, and results. With LoadRunner, you’d have to use a file system (which is frankly easier to navigate, use, and manage)

There are some good points in that enterprise column that are applicable to PC IMO. The bottom line is that there are some major capabilities that PC has and if you want them, there’s only one way to get them. I think the install base would be much larger if the price was significantly reduced. It seems a lot of HP LoadRunner customers are migrating to PC just this year, so the install base has grown significantly as of late.

Almost every project I work on has offsite LR resources, as of late. In most cases, they do not use PC. They just RDP into the Controller box. This is including HP PSO projects. It may violate the EULA, but EVERYONE RDP’s to LR machines and HP doesn’t care.

I forgot one more course:
- Using PC11: Designed for performance testers and PC administrators. This course is already fully developed and has approx 21 hours of content including labs. No scripting, just using PC11 and administration of PC11. It is great for those moving from PC 9.x to 11 as well as LR to PC.

Hi all. It’s been over 6 years since I taught this course (one semester only) at Georgia Tech. It was a lot of fun, but I had to travel and could not continue to commit to being in town every Tue and Thu, so I had to make it a one shot deal.

I’m more or less in the same situation now. I travel 3-4 days a week. However, if I thought there was enough interest in some ideas I’m mulling around in my head, I may rearrange my schedule sometime in the future.

Would any of you be interested in the following subjects if the course(s) were conducted remotely in the late afternoon/evenings and were very interactive? Perhaps you have clients who would be interested and/or you may be interested in doing so presentation yourself.

Please contact me at bwilson at techsouth dot com if interested. I don’t have any immediate plans right now, but would like to develop some consultants, thus the interest in doing training in some of these areas. I am setting up a PC11/ALM rig that will be RDP-accessable, as well as an SAP environment also RDP-accessable. If there was enough interest in any of these areas, I’d create the course. I have lots of content from which to start, but productising learning is a time-consuming endeavor.

- Performance Test Planning: Entire course would just be about PTP planning best practice with lots of real world examples, artifacts, etc. This would include PTP project/resource managing.
- Test Monitoring: All about what to monitor, how to monitor and why to monitor. I would probably use .Net and SAP for interactive examples
- LoadRunner Scripting for SAP: GUI and EP (Enterprise Portal) scripting including a team project using my environment. Most of the time will be spent of EP, of course. Those who excel will certainly get project offers from me. ; ) Must have very solid scripting skills to enter this coure; mastery of advanced techniques and concepts will be assumed.
- Value Added Results Analysis: Root cause analysis of complex results not only using LR Analysis, but using other tools and techniques.

The two also have different license models. If you need remote access, from offsite, then you are pushed to Performance Center if you choose to maintain license compliance with the standard/non-custom license model. This is an oft overlooked item when contemplating securing off site resources for your loadrunner skills.

I’m sure you could write it in less lines of Perl, but would anybody be able to read it? ;)

Awk rocks, used to use it a lot. I notice these days though, the data matches the tools more, so I haven’t had to reach for it in a long time.
