submitted by sdorman(1415) 1 year, 8 months ago

Performance should be treated as a first class requirement of any application. Different types of applications will require more work in this department, but every app needs to have this a major concern when designing the archetecture. read more...

.NET CF Performance Best Practices(jsprunger.com)

submitted by dayman(80) 2 years, 3 months ago

The impact of performance is much more readily apparent in .NET Compact Framework applications. The mobile devices commonly have a CPU that is 10 times slower than your desktop CPU, and possibly up to 100 times less RAM than a desktop or server. In Agile or XP development, the mantra is often to ignore performance considerations until necessary – I don’t think you can apply that to .NET CF... read more...

7 tips for for loading Javascript rich Web 2.0-like sites super fast(msmvps.com)

submitted by oazabir(1805) 2 years, 6 months ago

When you create rich Ajax application, you use external JavaScript frameworks and you have your own homemade code that drives your application. The problem with well known JavaScript framework is, they offer rich set of features which are not always necessary in its entirety. You may end up using only 30% of jQuery but you still download the full jQuery framework. So, you are downloading 70% unnecessary scripts. Similarly, you might have written your own javascripts which are not always used. There might be features which are not used when the site loads for the first time, resulting in unnecessary download during initial load. Initial loading time is crucial – it can make or break your website. We did some analysis and found that every 500ms we added to initial loading, we lost approx 30% traffic who never wait for the whole page to load and just close browser or go away. So, saving initial loading time, even by couple of hundred milliseconds, is crucial for survival of a startup, especially if it’s a Rich AJAX website. read more...

System.String Vs System.Text(programming360.blogspot.com)

submitted by syedtayyabali(135) 2 years, 10 months ago

Strings of type System.String are immutable (read-only) in .NET because its value cannot be modified once it has been created. That means any change to a string causes the runtime to create a new string object and abandon the old one. That happens invisibly. Following code allocates three new strings in memory: Example: string str = "This is Programming360 Blog. "; str += "It educate technical communities. "; str += "It believes, one concept at a time..."; Only the last string has a reference; the other two will be disposed of during garbage collection. Avoiding these types of temporary strings helps avoid unnecessary garbage collection, which improves performance. There are several ways to avoid temporary strings: * Use the String class's Concat, Join, or Format methods to join multiple items in a single statement. * Use the StringBuilder class to create dynamic (mutable) strings. The StringBuilder solution is the most flexible because it can span multiple statements. The default constructor creates a buffer 16 bytes long, which grows as needed. You can specify an initial size and a maximum size if you like. Example: System.Text.StringBuilder sb = new System.Text.StringBuilder(); sb.Append("This is Programming360 Blog. "); sb.Appen("It educate technical communities. ";); sb.Appen("It believes, one concept at at time..."); read more...
