I asked ChatGPT the question "How can I detect the network slowness in pcap file". I think you can learn from doing that yourself and read the answer.

I'll share the first bit of the answer:

  1. Analyze Packet Latency (Round-Trip Time - RTT) Measure the time between sending a request and receiving a response (e.g., TCP handshake or HTTP response). In Wireshark: Use the Statistics > TCP Stream Graphs > Round Trip Time Graph feature. Look for spikes in RTT. Use filters like tcp.analysis.ack_rtt to display RTT values.
