I was very excited about the release of OS X El Capitan earlier this week. The OS upgrade is highly recommended as it vastly improves the performance of Macs (that are capable of running Yosemite). However, my experience with the upgrade process was not a pleasant one. It was only a few hours back that I was successfully able to upgrade my Mac. That was after the MAS download got interrupted 6 times in a row, and I had wasted more than 15 GB of data on a single download of 6.08 GB.
