Ubuntu 23 on Windows 10 Slow

[Mo_Ta]

This is fresh Ubuntu 23 Image, running on Vbox 7.0.12.
Guest OS windows 10 Laptop: HW conf: i7 , 16GB, SSD; operating on Max performanec plan, Always on power adapter.
Simplest tasks on Linux takes time to load, like linux setting, loading broswer ...
Vbox conf: Conf: 2 VCPU, 8Gb allocated to the guest OS

Are there any miconfiguration causing this reposne time, or this is the expected performance from this machine
attaching VBox.log


Thanks
