Using a SASFILE Load command to move a large SAS data file into machine memory causes macro functions to slow down. Unloading the Data file from memory returns the memory to the available pool, but the macro functions continue to perform slowly.

If loading a very large SAS data file, relative to available machine memory, in to memory with a SASFILE statement, certain macro functions can be negatively impacted. Clearing the data file from memory does not solve the problem.
