Why application/process takes very long time to launch in macOS Catalina?

Hi,


During my software Installation process, four services and two plug-ins are launched to finish the installation task.

When I install my software in macOS 10.14 and lower, installation time is very less, but when I install my software on macOS 10.15 beta installation process takes long time to finish it.


Below is Installation summary on macOS 10.9:


Installer[1684]: Finalize disk "Macintosh HD"

Installer[1684]: Notifying system of updated components

Installer[1684]: **** Summary Information ****

Installer[1684]: Operation Elapsed time

Installer[1684]: -----------------------------

Installer[1684]: disk 0.04 seconds

Installer[1684]: script 0.06 seconds

Installer[1684]: zero 0.03 seconds

Installer[1684]: install 43.73 seconds

Installer[1684]: -total- 43.87 seconds


Below is Installation summary on macOS 10.15 beta:


Installer[610]: Finalize disk “Catalina HD"

Installer[610]: Notifying system of updated components

Installer[610]: zero 0.00 seconds

Installer[610]: install 450.79 seconds

Installer[610]: -total- 450.80 seconds


On Activity Monitor it seems that process launched during installation takes too much time to launch on macOS 10.15. Why does this happen?

Can you please guide how to increase the performance of installation on macOS 10.15 beta?


Note: my Installer (.pkg) file is Notarized.


Thanks in advance !
