Hi Guys ,
 
we have physical standby database for one of our biggest database. Scripts ship 
the archived log to standby server and then using parallel 32, manual recovery 
is performed (thru scripts) . Archived log size is 2 GB and daily production 
archive generation is aorund 2.5 TB. We are trying to increase performance on 
our standby database. We tried tuning various standby related parameters and 
IO, maximum apply rate we could achieve is 45 sec per archive log.  Can you 
suggest any other tunings you may have seen in your environments ? any pointers 
are appreciated ..

thanks
kapil Vaish
