Boosting Dropbox upload speed and improving Windows’ TCP stack
One of the best ways to find ways to improve performance, we’ve found, is to work closely with our customers. We love shared troubleshooting sessions with their own engineering teams to find and eliminate bottlenecks.

Really interesting debugging story and technical read. I just learnt a bunch more about networking!
“This was an eye-opening experience for us. We saw how far behind Linux is on the tracing tooling side. Even with all advances on the eBPF front, there’s still no unified format in Linux for collecting traces across all kernel subsystems. tcpdump is an awesome tool, but it only provides insight into what’s happening on the wire—it can’t connect that to other kernel events.
netsh trace, on the other hand, correlates events on the wire with events that happen on the TCP layer, timers, buffer management, socket layer, and even the Windows asyncio subsystem (IOCP).”
