Hi Gurus,

I need your help in my onbar restore. I am doing redirected restore from machine 1 to machine2(DEV). This is the first time i encountered so so so so slow restoration. It's working but a 10 GB restore will took me 10 hours.. Here's the onconfig file.

I hope someone can analyze and share their knowledge. IDS 9.4UC6 on Solaris 5.x
