HSG80 stripeset performance

Admins,

I have a stripeset that has very large file, continuous writes. The write performance is poor, and I'm wondering if increasing the stripe size (chunck size) would help. Here are the specs:

GS80 connected via switched SAN to EMA1200- Multi Bus Failover HSG80s

Stripeset is made up of 6 72GB, 15K disks, and has a default 256 block chunk size.

The entire dsk is used in a single volume/fileset.

---
Given that this is for writes only, and the writes are large and continuous, should I increase the chunksize of the stripeset, and increase the write block size of the file domain in advfs?  What factors do I need to consider when choosing a chunksize (i.e. disk geometry, cylinder, etc.)?  The StorageWorks books arn't real helpful.
-Thanks
