Bitfusion depends on fast and reliable networking. Ordinarily, the TCP retransmission rate should be very low and near zero. If TCP retransmissions are significant, it can result in poor performance. If there is poor performance in the Bitfusion environment, check for high TCP retransmission.
To check for high TCP retransmission rates, use the iperf3 utility. This utility may need to be installed on clients and servers if not already present. iperf3 will send traffic between endpoints and report on networking statistics. To use iperf3 to check for network statistics run the following commands:
Bitfusion Server |
Bitfusion Client |
iperf3 -s |
iperf3 -c <server IP address> |
All results are examined from the client side of the test. After allowing the utility to collect data and show results, you can terminate the server by running “CTRL+C” in the terminal where the server is running.
If TCP retransmission activity is frequently or constantly observed, this is the likely cause of poor Bitfusion performance. To help address TCP retransmission issues, here are potential avenues for further investigation:
