Ubuntu guest runs very slow with VBox 3.2.0

Description
I installed VBox 3.2.0 on Windows 7 64-bit, Intel i3 laptop.
When I installed Ubuntu 10.04, it took hours to finish and took minutes to boot to shell.
Then I removed 3.2.0 and installed 3.1.8, using same vdi and VM configuration, it took 5 sec to boot to shell. Other operation noticeably ran faster in VBox3.1.8.
The log attached.

Yes, disabling nested paging does make big difference as Guest is pretty much usable. I also notice that in 3.1.8, nested paging is enabled.

Could you attach the log of a 3.2.0 session with nested paging disabled? Can you confirm that performance is as expected with nested paging off or not?

Let's continue in #6716 as this is clearly a duplicate. Thanks.

for help on using tickets.
Does it make any difference if you turn off nested paging?
