I think you (and also Paul) got my idea basically ;) Why do dumb polling when it can be handled internally in owserver (owlib) > Now comes the question of what types of things to poll for: coming > and going of devices, either all or by family events from binary > inputs, by all, family or device min/max thresholds on value > things IMHO full/max-speed for iButtons (used as push-on devices) and I/Os like DS2406/08/13, the remainder could be/remain "slow" > > The final question in my mind is about polling interval.

The real problem (for me) is that the uncached search takes longer as it should, USB and CPU are million times faster than 1w.. The current solution & remainder is simple: I ask one DS18x20 (parasitic this could take 750ms, sure, but it currently takes 1s - even when its on another busmaster), then check for iButtons + IO's, then the next one but I want to multithread this task and that doesnt get faster with multiple BM :( Michael -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with undefined - http://www.enigmail.net/ iEYEARECAAYFAlDefisACgkQaWRHV2kMuALh9gCcDQvyyQfUs3upMY3bDnciShU0 ZDgAoOtGLCD4sb/QS+isOGpOZlod4uDg =lYS4 -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
