Time respond with HDR filters

Hi guys.
Since my update to Mac OS Mojave 10.14, the working time on Nik Collection HDR filters is very very long.
When I click via CC2020 on a Color Efex pro, Analog, Viveza, sharpness filter it takes 5 seconds to open the filters window mentioned above, when I choose HDR, it takes about 70 seconds !!
Here is the response I received from support:
First, HDR processing is much slower than processing in other plugins. The algorithm is more complicated. We plan to make improvements in future versions if technically possible.

What do you think ?
Didn’t I have this problem before?

Thank you
David
