I have a Panads code that runs for over 1hr to be able to churn out the output. When i ran it initially my comp had 16GB of RAM and the task manager showed that around 80% of Memory was being used when the script was running. I just now upgraded my RAM to 64GB. However now when i run the code there is no improvement. The system does not use all the memory available. Right it is showing that memory useage is around 30% and CPU useage is around 10%.

How can i increase the usage of memory to expedite the script execution
