Is it me or is FreeBSD slower on Xen than Linux?

Apparently, it's in
cat /proc/mounts

/dev/mapper/system-lvm--tmp /tmp ext4 rw,relatime,data=ordered 0 0
/dev/mapper/system-lvm--var /var ext4 rw,relatime,data=ordered 0 0
/dev/mapper/system-lvm--home /home ext4 rw,relatime,data=ordered 0 0
/dev/mapper/system-lvm--varlog /var/log ext4 rw,relatime,data=ordered 0 
0

But I don't really want to mount it asyncronous.
Would it help to have journaling?

Or is soft-updates already the "optimum"?
