LocalLB::ProfileTCP::get_cmetrics_cache_state

Introduced : BIG-IP_v9.4.0
Gets the states that if true, use the route-metrics cache in order to jump-start congestion-control parameters. When this parameter is disabled, the system slow-starts to the peer every time (assuming, of course, that slow-start is enabled), resulting in a much more conservative ramp-up in bandwidth utilization. This may be required in cases where an intermediate device is NATing multiple distinct clients to the same IP address, yet each of these hosts has distinctly different bandwidth and jitter parameters. It may also be required when the link is heavily oversubscribed and dropping packets due to overdriving.
