Veritas is awesome, but I would be suprised it it was faster than ext3 
or zfs for random sequence of read/writes - ZFS is using WAFL (Write 
Anywhere File Layout) VxFS is Extent-based (sequential allocation). 
Symantec says VxFS is 3x faster than ZFS, Sun is saying the opposite is 
true, both use favourable benchmarks to support it:

I've used it at home (OpenBSD) for years, without any problems, but there 
are echos in the mailing lists warning those who want to trust if on 
systems that do a lot of file ops. On the other hand, it was designed to 
deal with lots of small files...

and some ZFS propaganda straight from SUN. I keep hearing that ZFS will be 
an awesome FS, but it's not quite ready yet for Production use. Hardly 
suprising, given that it was out for 2 years or so.

lopsa might be a better place for such question:
