You really like to wait for hours before fsck will finish checking for
your volume?
While it's true that fsck on large filesystems takes ages soft updates
and background fsck makes it a lot less bothersome than it used to be.

I even went as far as disabling the cache flush option of ZFS through
this variable: vfs.zfs.cache_flush_disable: 1, since I already have the
write cache of the controller. I've also set some other variables as per
the Tuning guide but

Note: you might be in trouble if you loose your ZIL, thus the doubling up. I
*think* you can SSD a cache without risking dataloss, but don't take my word

Let me summarize this. ZFS will work even without ZIL or cache. Losing
ZIL will make you LOSE
I have a new server that I would like to use as a back-end Maildir
storage shared through NFS. The specs are:
FreeBSD 9.0 Beta 2
Xeon x3470 @ 2.93 quad-core CPU
4 GB Ram @ 1333mhz ( upgrading to 12GB tomorrow )
3WARE 9650SE-16LP card with write cache enabled ( battery is installed )

Is zfs supposed to be faster if you let it manage the disks directly ?
Not necessarily faster (in fact, RAID-Z variants have known limitations
which are not so pronounced in RAID5/6), but definitely more convenient
and in some respects

I know it's usually a big no-no but since I have the battery backed-up
write cache from the raid card, can't I just disable the ZIL entirely ?
No. ZFS doesn't work the way traditional filesystems do.

You can't ask for advice, get it, do something completely different, and then
complain that it didn't work.
Neither can you ask people to donate their time, if you won't spend yours.
In other words: if
