OSX guest extremely slow performance

[gattu marrudu]

Hi there,
I am running OSX 10.6.6 on an Arch linux host.
It installs fine, and the first day I used it was ok.
Since today, the performance has become so slow that the system is unusable. I don't know if I modified some significant settings on the VM.
Just dragging windows around is unbearably clunky, menus appear after 1-2 seconds after clicking, as well as switching between Finder windows or browsing through them . Booting takes forever. Reinstalling is 10x slower than normal (more than 2h instead of the 14m expected)
I tried several options, including reinstalling from the DVD iso, but after 2 hours it was still installing.
A windows XP guest runs much more smoothly on the same host, even with the other guest open.
I also tried a pre-installed version on a vmdk image and it was even worse.

Host configuration:
Arch Linux 2.6.37
Mobile Intel Core2 Duo T9400@2.53GHz
4Gb RAM
NVidia Quadro FX770 graphics with 512Mb RAM

VM configuration:
Machine: OSX Server
RAM: 1024Mb (tried up to 1536Mb)
Chipset: ICH9
IO APIC: on
EFI: Off
UTC clock: Off
Abs pointing device: On
PAE: On
VT-x: On
Nested paging: On, but it shows disabled in status bar when the VM is running
Video: 64Mb, no acceleration
Storage: SATA controller, AHCI, tried both with and without host IO cache
Primary hard disk: 20Gb
Audio: Off
Network: bridged, eth0
USB: 2.0 enabled

I tried several other combinations too but I can't improve performance anyway.

Any hints?
Thanks
gm
