title: Quartz vs "Reactive Extensions"
body: <p>I am looking for a scheduling library for C# and for a long time I though the "only" option is Quartz.NET which is quite robust and work just fine. But when I found "Reactive Extensions" (RX - <a href="http://msdn.microsoft.com/en-us/data/gg577609" rel="noreferrer">http://msdn.microsoft.com/en-us/data/gg577609</a>) I realized that it can do Time-Related operations as well and have native .NET frontend. </p>
  
  <p><strong>What are the limitations of Rx in terms of Time-Related operations?</strong> I need to fire tasks repeatedly in specific interval, after time period or so. </p>
  
  <p><strong>And are there any major differences?</strong> (in terms of performance etc. - for example by my experience Quartz freezes when there are more then 1500+- tasks scheduled)  </p>
