I get 20-30MB/sec with the inline copy from our DSSU. Without the inline copy, the speed is 40-50MB/sec. So yes, we see the 50% speed hit. Not sure why.

I have a customer which has a problem similar to this one: http://www.arcknowledge.com/gmane.comp.sysutils.backup.veritasbu/2005-12 /msg00502.html <http://www.arcknowledge.com/gmane.comp.sysutils.backup.veritasbu/2005-1 2/msg00502.html> And would like to know your experience on ITC.
