Guidelines for Scalability Testing:
• Scalability should increase by 50% when the number of CPUs
is doubled. This test is applicable for CPU intensive product.
• Scalability should increase by 40% when memory is doubled.
This test is applicable for memory intensive product.
• Scalability should increase by 30% when the number of NIC
cards are doubled. This task is useful for network-intensive
product.
• Scalability should increase by 50% when the I/O bandwidth is
doubled. This test is useful for I/O intensive products.
