SLOW ORACLE SAN BACKUPS - BEST PRACTICES

Hi Guys,

I´m facing some performance problems with oracle san backups, sometimes the rate is 120000 Kb/s and sometimes is very slow like 50000 Kb/s. 

I´m attaching the oracle tab so you guys can give advice about configuration.

The oracle database is about 5 TB

The client is AIX 7.1, the netbackup client version installed is 7.7.2, master is 7.7.3, media is an 5230 appliance (2.7.3)

What does bptm log report wrt buffers?
Look for buffer size and numbers at the beginning of each backup stream. 
Look for ...waited for full/empty buffers... at the end of each backup stream.
