My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

You saw the first iteration in April 2013 with the launch of Local Secondary Indexes (LSI). To speed up queries on non-key attributes, you can specify global secondary indexes. So when we launched in January 2012, we provided simple query functionality that used hash primary keys or composite primary keys (hash + range).

The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively. Recall that single-core performance most directly translates into speed on the web. Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge. Tap for a larger version. How bad is it?

You need a business stakeholder buy-in, and to get it, you need to establish a case study, or a proof of concept using the Performance API on how speed benefits metrics and Key Performance Indicators ( KPIs ) they care about. Start Render time, Speed Index ). Treo Sites provides competitive analysis based on real-world data.
