Performance-Time Calculation Incorrect

[Madhu]

Support,

I'm exploring 'Performance testing' feature comes with R2 release.

I see tool calculating time differences wrongly. Test log showing correct timings but performance window overview showing incorrect timings.

Log showing: 40Sec to load
Performance Overview showing: 639ms to load

Please see attached screenshot.

Thanks,
Madhu.

Hi Madhu,

Thanks for the feedback on our new Performance feature. The difference you see in time between these two areas is actually expected:

•  The time between steps in the Test Log is an absolute time, accounting for the entire Test Studio infrastructure. This includes overhead tasks such as maintenance, reading data, writing into the log itself, etc.
• The Total Time figure in the Performance Overview is a relative time, which isolates the timed action from that step down to the lowest level. It contains none of the Test Studio overhead time and gives you a more accurate figure that truly represents the time spent between Server and Client.

I hope this makes things more clear.
