Dear Sun Gurus,

We have an A5200 with VM 3.5 on top of it configured with a couple of
RAID5 volumes (one is 500G), which house a lot of very small
files. Customer has been complaining about how slow the setup is (file
system is vxfs, block size is 4k, stripe size is 128k). Customer is happy
about performance with large files. A5200 is connected to an E420r via
fibre, arbitrated loop.

I don't know where to start to try to optimize IO. Anything we can do at
all?

Any advice or pointers appreciated.

Thanx.

(will summarize)
