VirtualBox has the widest range of host system support and has
the lightest hardware demands, and excels for single PC personal
virtualization needs, but requires more UNIX/Linux command-line skills
when used as server virtualization solution. VMWare 2.0 has an
excellent web-management UI with the lightest client payload, but this
comes at the expense of heftier hardware requirements for good
performance and a fatter software drop on the server.[Read More]

Below is the excerpt from the articles for 3 comparison of ZFS against VxFS, Linux Ext3 and NTFS.
Solaris ZFS vs VxFS
In many cases, Solaris ZFS performs better at the initial release. In
some cases Solaris ZFS does not perform as well — but in almost all cases Solaris ZFS
performs differently. These results, as well as supporting testing data described in this
document, strive to give organizations sufficient detail on the differences between
Solaris ZFS and the Veritas File System so that intelligent decisions can be made about
when each technology could or should be used. Indeed, the results presented here can
help enterprises reach performance goals, if the goals can be quantified.
Solaris ZFS vs Linux Ext3
Testing results reveal:
• Solaris ZFS outperforms the ext3 file system in tests that represent the storage and
data requests typically made by database, mail server, and Web applications.
• The various ext3 file system mount options available require making a trade-off
between data integrity and performance — creating implications for environments in
which continuous access to data is critical. Such trade-offs are not necessary in
Solaris ZFS.
Solaris ZFS vs MS Windows Server 2003 NTFS
Solaris ZFS outperforms the Microsoft Windows Server 2003 NTFS file system by a
factor of 1.99 to 15, depending on the test.
• A 2 TB Solaris ZFS file system can be created in 17.5 seconds using two commands. In
contrast, creating a similarly sized Microsoft Windows Server 2003 NTFS file system
involves extensive command line or graphical user interface interaction and takes
nearly four hours to complete.
• Testing of multiple disk arrays was limited due to the inability to create volumes
containing more than 32 disks in the Microsoft Windows Server 2003 environment.

I'd like to make my MacBook the surfing monster--uploading/downloading at its top speed. Well, something need to be modified.
(1) Use Optimized version of Firefox (http://www.furbism.com/firefoxmac/) -- Bon Echo
(2) Tuning VNodes and TCP buffer : (issue these command in Terminal)
sudo sysctl -w kern.maxvnodes=92160
sudo sysctl -w net.inet.udp.maxdgram=65536
sudo sysctl -w net.local.stream.sendspace=256960
sudo sysctl -w net.inet.tcp.sendspace=224360
sudo sysctl -w net.inet.tcp.mssdflt=2920
sudo sysctl -w kern.ipc.maxsockbuf=1048576
sudo sysctl -w net.inet.udp.recvspace=265152
sudo sysctl -w net.local.stream.recvspace=224360
sudo sysctl -w net.inet.tcp.recvspace=256960
sudo sysctl -w kern.ipc.somaxconn=1024
sudo sysctl -w net.inet.tcp.rfc1323=1
(3) For Bon Echo, download the add-on called 'Faster Fox' (http://fasterfox.mozdev.org/), set its Preferences to 'Turbo Charged'
(4) Use speed test to verify (don't forget to clean up your browser DISK and Memory cache EACH start)

If you want to run Windows or other OS on your Intel Mac, there are few commercial softwares out there to buy such as Parallel Desktop, VMWare.
Unlike Parallel desktop and VMWare, Virtual Box (http://www.virtualbox.org/wiki/Screenshots) is FREE.
Give it a try. I myself haven't had any time to try. Will do soon.

MS Word on Mac OS X will optimize its font menu every time it started up, this process takes quite some times and can make you feel very bore especially for one who has just moved from Windows to Mac platform.
So, to minimize this effect (shorten launch time), we can disable the WYSIWYG from General option.
Goto 'Preferences.." ==> click "General" ==> uncheck "WYSIWYG font and style menu"
See picture here .
