| Back in May, we [announced](https://blog.golang.org/2011/05/go-and-google-app-engine.html) |
| the Go runtime for App Engine. |
| Since then, we've opened it up for everyone to use, |
| added many new APIs, and improved performance. |
| We have been thrilled by all the interesting ways that people are using Go on App Engine. |
| One of the key benefits of the Go runtime, |
| apart from working in a fantastic language, |
| is that it has high performance. |
| Go applications compile to native code, with no interpreter or virtual machine |
| getting between your program and the machine. |
| |
| Making your web application fast is important because it is well known that |
| a web site's latency has a measurable impact on user happiness, |
| and [Google web search uses it as a ranking factor](https://googlewebmastercentral.blogspot.com/2010/04/using-site-speed-in-web-search-ranking.html). |
| Also announced in May was that App Engine would be [leaving its Preview status](http://googleappengine.blogspot.com/2011/05/year-ahead-for-google-app-engine.html) |
| and transitioning to a [new pricing model](https://www.google.com/enterprise/cloud/appengine/pricing.html), |
| providing another reason to write efficient App Engine applications. |
| |
| To make it easier for Go developers using App Engine to write highly efficient, |
| scalable applications, we recently updated some existing App Engine articles |
| to include snippets of Go source code and to link to relevant Go documentation. |
