| 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. | |
