I apologize but I have not yet been able to successfully build QEMU on Windows, even after mucking with the mingw stuff. I probably need to spend more time on it at some point. But if anyone is using Windows and can compile QEMU from source, you can try moving the Sleep to see if that helps, especially after applying Ken's new patches. Actually Kazu's patch for TAP performance addresses this for TAP for example, so it should be easy to adapt to slirp... the code is in very close proximity.

The "qemu-slirp-performance" patch contains three improvements to qemu slirp networking performance. Booting my virtual machine (which NFS-mounts its root filesystem from the host) has been accelerated by 8x, from over 5 minutes to 40 seconds. TCP throughput has been accelerated from about 2 megabytes/sec to 9 megabytes/sec, in both directions (measured using a simple python script). The system is subjectively more responsive (for activities such as logging in or running simple python scripts).
