Hello,

I have reinstalled it with GPT/ZFS and your right it's much better. Same search 
taking 3-6 seconds so I have deleted now all my old UFS based FreeBSD images.


If the partitioning alone changed something it was probably an alignment 
problem. These are things you can try:


* Create a VM with two virtual disks.

* Install a UFS system on the first disk.

* Create and mount a UFS on the unpartitioned second disk.

* Copy the whole system with tar to the second disk.

* Reboot the VM.

* Compare performance on both file disks.

Maybe your virtual disk backend is is just terrible with unaligned accesses.

 Hello, Freebsd-stable.
 
 Does FreeBSD 8.0 support IPSec NAT-T in transport mode?
 I want to create a L2TP/IPSec server. My VPN clients are NATed.
 L2TP server (MPD5.x) makes tunnel, so I need working IPSec NAT-T in transport 
 mode.
 Thanks a lot.
 

Yes the NAT-T Patch has been integrated into FreeBSD 8.0.

Just rebuild your kernel with this options:
device  crypto  # IPsec depends on this
options IPSEC
options IPSEC_DEBUG
options IPSEC_NAT_T
