Hi,

I am using DART panel to calc the PFM hysteresis.
I chose every point in a 32x32 map,1024 points in total, and wanted to calc every point's Ampd, Phasd,QFac and Freq0 without the graph. I found the PZTHyst.ipf and deleted the graph command.
The calc speed was fast at the beginning, but it became slower and slower when more points were calculated. It took more than 24 hours to calculate 1024 point's PZTHyst.
I am going to calc bigger map in the following. I am afraid that the calc would be too slow or even shut down.

Is there any method to develop the calc speed?

Thanks!
