A best-case environment has zero packet loss and very low or no network latency. For maximum throughput, a best-case traffic profile would consist of very long-lived connections with very high utilization and virtually no delay in client or server responses. An ideal example might be a corporate, local-access, OS update server only serving large, static files. Obviously not particularly common.
It isn't possible to determine if the device is underpowered without knowing any of the system stats. Here are a couple things I would check.
- What does your CPU utilization look like? Is it peaking, or do you hit your peak throughput before you hit 90% CPU utilization?
- You mentioned 200K connections, how many new connections/sec are you getting?
- Do the /var/log/ltm or /var/log/tmm files have any interesting messages?
