There were some legitimate concerns about Drupal 8 potential performance regressions as a result of being built on top of Symfony2. Drupal 8 Beta-14 is the latest release; It seems that the Drupal 8 big release it comes apace. As per all the benchmarks I saw until I noticed that Drupal 8 is much slower than Drupal 7 especially for logged in users which is kind of a bummer.
Isn't Drupal supposed to be used for online communities where logged in users could interact? For displaying news and blogs there are already other software much convenient to use such as Wordpress. What kind of server would support such an expensive product? In this scenario, will be Drupal 8 a solution for high traffic online communities where logged-in users could post things and make comments and interact with each other?
Shouldn't this newer version of Drupal better than the old one? In terms of performance it doesn't seems so. This is why I'm thinking to find alternatives to Drupal for my potential clients. I'm not sure that financially speaking would worth to develop an online community website in Drupal and pay a lot for hosting and development.
