HA is slow after move to ssd

Hi,
i moved my ha installation from sd card to a argon m2 ssd case with a wester digital M2 sata ssd disc.
I does a complete backup of my ha system. Reinstalled on my new ssd the blank HA system and after booting it restored my backup.
This works great. But now, i see that the system runs much slower than with sd card.

For example, node red addon starts in under 3 seconds. No it takes 8 - 10 seconds.
What goes wrong here? How can i find out, whats wrong? Or has someone any ideas?

Do any of your logs say anything? Errors due backup restored incorrectly might slow the system down.

after one day it seems to be fast again.
