Unconnected. Ran with f88ad220eb149fd (I think) on Windows
No sleep in between but also no I/O Unconnected on Windows, Connected on ReactOS. Ran with 76547832377 (removing device in PnP handler) ReactOS: almost 50000 iterations (then some timer locked the system) Windows: 23749 iterations
Update: re-run after cleanup of primary/secondary code (create/destroy Windows device) Version: windrbd-1.2.0-rc6-76-g81df2298-pnp-cleaned-up17-drbd-9.0-x86_64 32050 iterations on Windows (unconnected) about 26 hours
When invalidated so it syncs a bit goal is to trigger free_page BSOD
On Windows (with 27GB disk): 59 iterations (about 20 hours) with windrbd-1.2.0-rc6 Were there any connection losses?
Dec 5-6 2024: with 2b417f71733a28de no connection losses 82 iterations about 20 hours

Dec 27-28: with cdc87c08 for drbd-9.1 (but checked 9.0 and 9.2 also) 18226 iterations (in about 22 hours) With focus on execution speed (average 5 seconds / run but reconnect sometimes takes > 10sec, which is probably also on Linux DRBD). So I would say fast enough.
Jan 3 - Jan 8 (843 iterations) about 9 minutes full sync time (26GB) Runs for 5 days now, no network interruption WinDRBD version is: windrbd-1.2.0-rc6-194-g51ea8b0a-no-send-packets-limit-drbd-9.2-x86_64
