Project Brief

New platform for KILROYs online marketing activities

Migrate content and URLs

Launched July 2011

Peaked at a 5 man development team

Still in active development - 1 week release schedule

Umbraco 4.7.1.1 (patched)

By the Numbers

7 languages (soon to be 8)

21 sites

30 content editors

94 master pages (templates)

100 razor macros

830 dictionary items

5000 images

26000 pages

33000 active nodes

700.000 monthly visitors

2.800.000 monthly page views

Theme 1: Using Umbraco

10,000 destination pages

Problem: create and maintain 10.000 destination pages.

Solution: common destination structure with automatic

creation of sub pages. And onPublish event update of JSON

data files.

Discussion

What do you do when you need to create a database

of stuff (e.g. staff list, product videos, events, etc.)?

Theme 2: Performance

The Umbraco Macro Cache - #h5is

Your are in big trouble, when you entire performance

strategy is the Umbraco Macro Cache…

"All non-trivial abstractions, to some degree, are leaky.

Abstractions fail. Sometimes a little, sometimes a lot. There's leakage. Things go wrong. It happens all over the place when you have abstractions."

Joel Spolsky, http://www.joelonsoftware.com/articles/LeakyAbstractions.html

The Law of Leaky Abstractions

A Robust Caching Solution

1. Use the standard ASP.NET cache

Problem: when we deploy or when the AppPool recycles, we loose the

2. Use Microsoft AppFabric.

It provides a distributed, in-memory, application cache service in

separate process than the webserver.

Problem solved: we have a persistent cache – even when the web

server restarts or the AppPool recycles

We update the cache OnPublish events or after timeout.

4 Quick Tips for Good (Razor)

Performance

…besides using custom caching :-)

Wisely use HasProperty and HasValue

if (myDynamicNode.HasProperty("myCoolProperty") &&

myDynamicNode.HasValue("myCoolProperty"))

int tmpInt;

if (int.TryParse(myDynamicNode.GetProperty("myCoolProperty")

.Value, out tmpInt))

Use DynamicNode Extensions and Razor common helper

public static class DocumentExtensions {

public static bool IsValidProperty(this DynamicNode doc, string propertyAlias)

if (doc.HasProperty(propertyAlias) && doc.HasValue(propertyAlias))

return true;

return false;

public static string GetPropertyAsString(this DynamicNode doc, string propertyAlias)

if (!doc.IsValidProperty(propertyAlias)) return string.Empty;

return doc.GetProperty(propertyAlias).Value;

public static int? GetPropertyAsInt(this DynamicNode doc, string propertyAlias)

Usage int? myIntProp = myDynamicNode.GetPropertyAsInt("mypropertyAlias");

Use Children if first level search

Be aware of performance when using DynamicNode.Descendant(docType).

Use "Children" if possible.

For example to get a direct child node :

Don’t use: DynamicNode dNode =

rootNode.Descendants("myDocType").Items.FirstOrDefault();

You can use instead : DynamicNode dNode = rootNode.GetChildrenAsList

.Items.FirstOrDefault(x => x.NodeTypeAlias == "myDocType");

Dynamic notation considered harmfull?

Be aware of performance using dynamic notation like node.DocTypeName =>

same problem as last slide.

To get a direct child node :

Don’t use: dynamic rootNode = new DynamicNode(xxx);

DynamicNodeList allMyDocType = rootNode.MyDocType; // can have performance issue

// PS : string myProp = rootNode.MyProp is OK is the prop exist

You can use instead: DynamicNode dNode = rootNode.GetChildrenAsList

.Items.FirstOrDefault(x => x.NodeTypeAlias == "myDocType");

Discussion

What is your hard learned tips for blinding fast

Umbraco performance?

What’s in Our Toolbox?

http://media.photobucket.com/image/toolbox/LilToe01/Shop/Toolbox017.jpg

Visual Studio 2010 (and Resharper)

Kiln (Mercurial)

Shared MS SQL Database

The Basics + a Tip

XmlCacheEnabled = false

Deployment

Web Deploy from Visual Studio

XML Config transformations

Updating Umbraco Doc Types and other settings

Two approaches:

Create an Umbraco Package containing every Doc Type, every

template, every macro and so on

Create an Umbraco Package containing new and updates Doc

Types, templates etc.

Discussion

How do you deploy?

Have you felt the pain of updating an highly utilized

DocType?
