Review Load Balancer machine type guidance for heavy Git operations (CPU / Network Bandwidth)

A customer has reported hitting network bandwidths on their HAProxy load balancer nodes on AWS when performing heavy and concurrent Git operations.

Network bandwidth is an involved area and can involve bursting algorithms based on best efforts. Recent internal testing data also shows CPU usage can also be impacted in very heavy scenarios such as large concurrent git clones.

Task is to review all load balancer machine type guidance to ensure they're correct and have enough headroom for most use cases.
