On our Gigabit Ethernet LAN (1000 Mbit), we get a transfer speed of around 4.7 MBps when copying a 20 GB file. Will this performance be suitable for R1Soft CDP?
It looks as if something is wrong with the environment, you have network or disk I/O issues. Normally, it should be from 100 Mbits to 300+ Mbits depending on the performance of the two computers connected to the LAN.
1. Check for packet loss. There may be errors counting on the switch ports (check by telnet to your switch).
2. Try a rapid ping of 20,000 packets from some type of trusted network device, possibly the switch itself, depending on the model.
3. Check for the percentage of TCP segments retransmitted.
On Windows, run netstat -s on both computers. Example:
12642 / 6152596 = 0.002, so 2/10 of a percent of the TCP segments were lost in the example. That is normal.
Amounts higher than 1% or 2% are possibly a packet loss issue, especially on your CDP Server, which mostly does only communication with the agent(s).
