Synthetics slow from tape

Hi

I have a problem when creating synthetic backups from images residing on tape on windows media servers.. The jobs run consistently at 4096 kbps and never go over this speed. I have run synthetics from tape many times from Linux media servers and never seen this consistently slow performance before. Due to the fact that the speed never goes over 4096kbps I can only assume some setting is throttling this.

Any suggestions appreciated.

Simon

hmm try to create /usr/openv/netbackup/NET_BUFFER_SZ with 262144 on Media Server and run backup again.
