Hi everyone, I'm experiencing some performance issues with my website https://premiumteamnames.com/, and I want to use Wireshark to analyze network traffic. Has anyone used Wireshark for troubleshooting website performance? What filters or techniques would you recommend to identify potential bottlenecks or slowdowns? Any insights would be greatly appreciated!
