> I noticed that my internal network was 100Mb/s, which was dreadful. Downloads of 500MiB files would take tens of minutes, because Tomcat would drop connections on such a slow download. And even without dropped connections it generally took a long time to download anything, and Zoom call quality was regularly degraded. Was you network setup broken? Did your firewall block ICMP? Ancient servers like tomcat and apache should handle slow networks in stride, even with modern updates - and 500MB at 100mbps is 40 seconds? Now I can't imagine running 100mbps today for a home network... So upgrading makes sense. But your problems doesn't sound like they were caused by your lan speed.
