Hi All,

Below is from AWR report and I was wondering if the CR Avg Time was on the slow side.

Anyone have any rule of thumb as to what it "should" be?

BTW, this is during the ETL load into our DWH.

Global Cache Transfer Times (us)

• Avg Time - average time of all blocks (Immed,Busy,Congst) in us
• Immed, Busy, Congst - Average times in us
• ordered by CR + Current Blocks Received desc
