A couple of days ago, I was briefed by one of the hired tuning expert, who was trying to investigate recently regarding a slow show shown by one of my production system, that the I/O throughput is miserable.

Although we are having a good setup with all IBM hardware, including the server, SAN switch, the storage but it is showing an average result of 40 mbps….And as per him this is the standard of I/O as of 9 yrs back….

Don’t know yet, where can I counter verify and know the current standards…..
