Typically, your issue is the result of provisioning your system with under powered Performance Center Data Processors. When selecting a platform to serve as the Data Processor, make sure that the machine has enough memory and strong enough CPU to handle the collating and processing of your test results.
It is the data processor that handles the processing of your test results when a scenario ends. I suggest that you monitor (using perfmon) the CPU, Memory, Processor Queue Length and Physical Disk Queue Length while you are trying to collate and analyze your test results. This way you will know if you have a resource contention issue on your Data Processor.
Keep in mind that the recommended HP configuration for Performance Center components is the absolute minimum. You should always use the most powerful systems that your company can afford.
If this is not the issue, please check the following:
- Error Logs
- Event Logs
- Anti-virus End Point Protection (This can slow things down)
- Do you have enough Data Processors to handle collating more that one test at a time.
If you need additional information, please include a greater level of detail. Include Error messages, System message, monitoring results from you Data Processors, OS and system configuration for the Data Processors.
There are many factors that can influence the speed of you test result processing.
