Я же блин на каждом углу об этом кричу: нельзя пользоваться alpine и надеяться на тот же перфоманс! glibc круто оптимизирован, хоть и огромен, musl же хорошо имитирует API, но перфомансные проблемы на нём возникают годами! (и будут возникать, думаю)
Тут такое дело: у меня warp под musl медленее в 2 раза, чем под glibc 232088 vs 594310 rps. Почитал в интернетах, оказалось так и есть. Так что любителям докера на основе alpine стоит задуматься. medium.com/rocket-travel/alp…

Look at this slice of awesome. The new Wireshark version in dev (3.3.0) has a packet diagram view.
A fantastic teaching and learning tool! When released, I'll be making pretty extensive use of this in my classes! Great job @geraldcombs and @WiresharkNews team.
