CPU Considerations on Different Teradata Platforms
Because software-based BLC is CPU-intensive, consider the CPU capabilities of the particular Teradata Database platform when using it. When using BLC on the Teradata 1650 and 2650 systems, which offer very high CPU capabilities, you can:
When using software-based BLC on other platforms with less CPU capacity, you may need to:
Some operations (including queries, insert/updates, ARC dump/restores, reconfig, and CheckTable) can use considerably more CPU while operating on compressed tables. Unless the system is very CPU rich, these operations will impact other workloads and could lengthen elapsed response times.
