Window Sweep

L->R and R->L indicates respectively the direction from local to
remote and remote to local.


TCP Throughput

L->R and R->L indicates respectively the direction from local to
remote and remote to local.

Window (KiB) indicates the total Max Window (1 KiB = 1024 bytes)
followed by the number of connections and KiB per connection in
parenthesis as follows: (n conn.@ n KiB).

Ideal L4
indicates the ideal TCP throughput metric.

Actual L4 indicates the average of actual TCP Throughput metric. The
pass/fail verdict icon is displayed next to the this metric when enabled.
A value greater or equal to the defined threshold gives a pass verdict.

