I have always found that iperf far exceeds the performance with NetBackup, even when as you suggest trying to use similar buffer sizes.
I think you may be better off testing with NetBackup. You can use the GEN_DATA directives to create data without involving disk read speeds: http://www.symantec.com/docs/TECH75213 you can then create a disk storage unit on the Media Server for your test policy and use the SKIP_DISK_WRITES touch file: http://www.symantec.com/docs/TECH69948 (Beware as that will disable it for all disk backups!) I have not myself tried this yet....but in theory it will just test the data transfer between the client and media server.

Hello Wonder what iperf settings best simulates netbackup, in regards to window size & parallel streams Thinking that the windows should be the same as NET_BUFFER_SZ & parallel same as active jobs Regards Michael ________________________________ This e-mail was sent by GlaxoSmithKline Services Unlimited (registered in England and Wales No. 1047315), which is a member of the GlaxoSmithKline group of companies.
