(b) Measurement result of the communication speed
The following table lists the time that takes until a file is read from a request source device to a request
destination device.
(2) When a request source device and a request destination device are connected
to an Ethernet adapter module
The results are based on measurement when FTP communications are performed with four modules connected
in star topology.
(a) System configuration
(b) Measurement result of the communication speed
The following table lists the time that takes until a file is read from a request source device to a request
destination device.
