Sequential Approach

Process 1:

• Fetch dataset 1 (30 sec)

• Process (60 sec)

Process 2:

• Fetch dataset 2 (30 sec)

• Process (60 sec)

Total: 180 seconds

Concurrent Approach

Process 1:

• Fetch dataset (30 sec)

• Process (60 sec)

Process 2:

• Fetch dataset 2 during Process 1

• Process (60 sec)

Total: 150 seconds (17% faster)
