One of the most ViewState heavy controls is the DropDownList. It stores in ViewState the Text and Value for every ListItem in the DropDownList. This means large Lists can get really nasty when ViewState comes into play. They also include all of these entries a second time because they're all in the html. Being in the html will only slow the page ...

I'll be presenting at the Northwest Ohio .NET User Group this evening at 6pm.  The talk will be a slightly modified version of my Black Belt ASP.NET Performance talk that I gave earlier this month at Tech Ed in Orlando.  According to their web site, the user group will also be giving away a Zune to one of the attendees of tonight's ...

I gave my Tech Ed presentation, ASP.NET Black Belt Performance Techniques, yesterday afternoon.  The talk was well-attended, with about 300 372in the audience.  I gave the talk last month in Cleveland and it was very well-received.  I promised attendees the slides and demos would be available on Tech Ed's CommNet, and right now ...

Last night I presented at the Cleveland .NET SIG on Black Belt ASP.NET Performance Techniques, which is a talk I'll be giving in a few weeks at Tech:Ed Developers in Orlando.  I was asked a couple of weeks ago if I could give a talk in May and I decided to do it so I could practice for TechEd.  Since this is a new talk for me (though ...

I'll be speaking at the Cleveland .NET SIG tomorrow night.  The topic is Black Belt Performance Tips for ASP.NET, which will be a dry run for a session by that same name I'll be giving next month at Tech:Ed Developers in Orlando.  Some of the primary areas covered will be advanced caching techniques and asynchronous programming ...

Hier mal in Stichworten ein paar Grundsätze die man beim Entwicklen beachten sollte, wenn Laufzeit-Performance eine Rolle spielt:C# Performance Optimierungen: Lieber wenig große wie viel kleine Assemblys„sealed“-Klassen wann immer möglich bei geerbten Typen mit vielen virtuellen Funktionen. Die virtuellen aufrufe werden ...

One problem I've noticed on a bunch of sites is a large amount of ViewState. I'm not going to sit here and explain all about ViewState. There are PLENTY of sources for information on that piece of technology. So in an extremely short description of what ViewState is I will say that, ''ViewState is a way of preserving the state of the 'Viewed' ...

I read an interesting little post about a Try Except Performance Test Using Python written by Patrick Altman. As he mentioned, I have also had discussions with people about this exact topic in the past plenty of times. He was testing the performance issue of whether it is better to use a try catch block to handle possible errors or to check for ...

Letztens musste ich die (zeitliche) Performance einer sehr CPU/IO lästigen Operation verbessern. Da die Operation in diverse kleinere Vorgänge unterteilt war musste ich die Vorgänge ermitteln, welche am meisten Zeit in Anspruch nahmen und das meiste Optimierungspotential hatten. Dafür hab ich eine Klasse entworfen die mit ...

If one is to write a well developed software application, one must have a fair bit of knowledge in the area of memory managament. It is important to understand the underlying technology which allows ...
