In the previous part of the series, we took a closer look at the event loop model. In this article, we are going to discuss several techniques that help you to prevent event loop delays.
The causes of event loop delays can be divided into two categories. The first category contains event loop delays caused by a handler calling a blocking API. The second category covers delays caused by a handler code taking a great amount of CPU time to complete. Let’s start with the first category and talk about blocking API calls.

If you have any type of Dell assets registered to a Spacewalk or Satellite server, like desktops, laptops, or servers, then there’s a very easy way you can get all of your assets hardware support information saved at Spacewalk or Red Hat Satellite. In case you didn’t know, Dell provides a web service that you can use to query support information, by just providing the service tag of an asset. This valuable information includes shipping date, region, model, plus start and end dates of expired and active contracts. Read more about the web service.
