What type of benchmark testing are you looking for?

Subject: [Veritas-bu] Tuning backups.

There are several ways to tune backups.

1. NET_BUFFER_SZ
2. SIZE_DATA_BUFFERS
3. NUM_DATA_BUFFERS

While these help a little, I found by reading the NBU6 optimization document I 
improved speed by 2x in some cases (need to do some more
verification) using 256k buffers in the kernel (Linux) st driver rather than 
the default of 32k and also using more of them.

Anyone here do a LOT of benchmark testing?

Justin.
