SSD slow APFS

[bugraduz]

Hello , There was no such problem when using the mojave operating system(HFS+). But with the installation of the catalina operating system(APFS), this problem occurred. Especially the boot time is too long and the desktop and dock freezes for 10 seconds when the computer is turned on, the computer doesnot react for a few minutes. The dock hangs when turning off the computer, the desktop freezes. I tried sudo trim force enable/disable , clover TRIM patch enable/disable.

It is APFS which Trims the whole disk on mount and unmount. Trimforce is only for SATA disk AFAIK. Nvme has always trim.

That said, I only experience delays on boot (the boot just takes long while it's trimming) and shutdown also.

You experience hangs during normal operation?

no. I only encounter this problem during boot, on the desktop when the computer is first turned on and during shutdown. Reading and writing values are normal when the computer is idle.
