It's important to consider the following points:
- During maintenance operations, scale units 2 through 10 maintain their aggregate throughput. However, scale unit 1 can experience slight variations in throughput during such operations.
- Regardless of the number of scale units deployed, if a single TCP flow exceeds 1.5 Gbps, traffic performance can degrade.
