Network Performance Utility

Scenario​

We aim to implement a utility to measure network performance similar to tools like iperf or speedtest. This utility will present metrics such as bandwidth (download and upload), network latency/response time (also known as RTT - round trip time) for various sites. Typically, the utility will establish multiple connections/transfers and display their average.

Respond to the following questions with "True" or "False" and justify the answer. The justification should be simple, 2-3 sentences for each answer.

Questions​

  1. The utility can use UNIX sockets for measurements. Answer: False

  2. The process started by the utility is I/O-intensive. Answer: True

  3. To function on systems with wireless connection, the utility needs to be started with privileged rights. Answer: False

  4. The process started by the utility will heavily use buffer cache. Answer: False

  5. The utility can be written in an interpreted language like Python. Answer: True

  6. For efficient operation of the utility's process, the limit of file descriptor table needs to be increased above 1024. Answer: False

  7. The process started by the utility will consume a lot of RAM. Answer: False

  8. To achieve the best results, the utility should be used at a time when other applications are using very little or no network. Answer: True

  9. Hardware interrupts will be generated during the use of the utility. Answer: True

  10. The process started by the utility will use shared memory mechanisms. Answer: False

  11. The process started by the utility is a component that requires additional security/isolation compared to other processes. Answer: False
