Frequently Asked Questions
Sometimes PTFB Pro consumes a lot of cpu
We've had one report that from time to time, PTFB Pro's cpu utilization rises to 50% or more and stays there, resetting only when PTFB Pro is quit then restarted. This report was for PTFB Pro 4 running on Windows 2003 Server in a virtual machine (specifically Virtual Box).
The following simple workaround provided a solution:
- Go into the Configure dialog (Options->Configure)
- On the settings page, first option, lower the Response speed to 50
- Close the configure dialog
- If necessary, quit then relaunch PTFB Pro
It may be that the virtual machine had not properly implemented the hardware timers that PTFB Pro uses to schedule its activities, leading to a situation where PTFB Pro's periodic checks for targets were running back to back with no downtime between. Lowering the response speed enabled PTFB Pro to return to its work/rest/work schedule, and the cpu utilization returned to normal.
