We are currently conducting a POC on Teradata’s 2690 with a ½ rack configuration. I was wondering how fast should we be able to pull data off the disk? Given a table of size 200G and running a simple query i.e. select sum(impressions) from table_imp. With no other queries running it takes 54 seconds to come back, which gives us about 3.7G/s. Does that seem about right?
