Web Performance Best Practices: How masters.com re-designed their site to boost performance – and what that re-design missed
posted by grabnerandigrabnerandi 1170 days, 1 hour, 31 minutes ago
Monday, April 05, 2010 3:08:19 PM GMT
Last week I blogged about the 6 Steps to identify the major web site performance problems on sites like masters.com. Unfortunately for me I did the analysis 3 days before they re-launched their website. The site looks really nice now – great job. They fixed some of the problems I highlighted in the blog and also follow more of the best practices outlined by Google and Yahoo. In order to give them credit for the work they put in I ran another analysis on the new site. It should be interesting for every... (more)

How Tiger Woods could crash the performance of www.masters.com – before the first tee
posted by grabnerandigrabnerandi 1176 days, 9 hours, 39 minutes ago
Tuesday, March 30, 2010 7:00:58 AM GMT
It used to be that the only people who would tune in for the Masters were readers of Golf Digest. This year, however, you can add to that base audience the readers of People, InTouch, and even the National Enquirer. While Tiger Woods may not appreciate all the increased attention, it can only help boost ratings for the Masters itself. The problem is that if all those viewers try to visit www.masters.com, they might find themselves waiting a long time to see if Elin turns up. In order to understand some ... (more)

In ASP.NET controls used in to the user controls are generate Client Id which unique for the control and If you have so many user controls hierarchy then you will have very long client id like ‘ctl00CPHctl02BMuserLogin_UserName’.It will increase the Kilo Bytes of html rendered in the browsers. Label control is the control which is used to display text and its render as span tag in the html render by the browser. So in such type of scenario if you have so many label controls then your html is going to... (more)

After my recent presentation at TSSJS – Performance Anti-Patterns in AJAX Applications - I got interesting feedback from one of the attendees: “The presentation was good but I thought you are talking more about actual problems with XHR/AJAX Requests”. I have to admit that I focused on all common problems of Web 2.0 applications – including network roundtrips, JavaScript and Rendering – and not just on those related to asynchronous communication. The comment made me work on a sample application where I wa... (more)

How to avoid the Top 5 SharePoint Performance Mistakes

SharePoint is without question a fast-growing platform and Microsoft is making lots of money with it. It’s been around for almost a decade and grew from a small list and document management application into an application development platform on top of ASP.NET using its own API to manage content in the SharePoint Content Database. Over the years many things have changed – but some haven’t – like – SharePoint still uses a single database table to store ALL items in any SharePoint List. And this brings me... (more)

One of my daily activities is checking interesting blog posts on various performance related topics. Today I stumbled across the blog 10 Cool Websites with Amazing jQuery Effects. I started looking at these pages which really have nice UI features implemented with jQuery. What many of these pages have in common is that they contain a huge number of images that are all hosted on the same domain. Depending on which browser you have this can result in long loading times of all images or other embedded objec... (more)

Linq to SQL: Delete an entity using Primary Key only
posted by omaralzabiromaralzabir 1197 days, 10 hours, 8 minutes ago
Tuesday, March 09, 2010 6:31:42 AM GMT
Linq to SQL: Delete an entity using Primary Key only Linq to Sql does not come with a function like .Delete(ID) which allows you to delete an entity using it’s primary key. You have to first get the object that you want to delete and then call .DeleteOnSubmit(obj) to queue it for delete. Then you have to call DataContext.SubmitChanges() to play the delete queries on database. So, how to delete object without getting them from database and avoid database roundtrip? You can call this function using Del... (more)

Linq to Sql solve transaction deadlock and query timeout problems using uncommitted reads

Tuesday, March 09, 2010 6:29:15 AM GMT
Linq to Sql solve transaction deadlock and query timeout problems using uncommitted reads When your database tables start accumulating thousands of rows and many users start working on the same table concurrently, SELECT queries on the tables start producing lock contentions and transaction deadlocks. This is a common problem in any high volume website. As soon as you start getting several concurrent users hitting your website that results in SELECT queries on some large table like aspnet_users table th... (more)

Optimize ASP.NET Membership Stored Procedures for greater speed and scalability Last year at Pageflakes, when we were getting millions of hits per day, we were having query timeout due to lock timeout and Transaction Deadlock errors. These locks were produced from aspnetUsers and aspnetMembership tables. Since both of these tables are very high read (almost every request causes a read on these tables) and high write (every anonymous visit creates a row on aspnet_Users), there were just way too many lo...

In Part I of this blog series I gave a general overview of BizTalk - the components that are involved in message processing and talked about how BizTalk specific performance counters can help spotting problematic areas. In this post we go beyond performance counters (even though we still need them) and take a deep-dive into adapters and pipelines.Step 2: Analyzing BizTalk Adapters On the incoming or receiving side of BizTalk – Adapters receive artifacts, e.g.: the File Adapter reads files from disk that...

Microsoft BizTalk enables companies to integrate and automate their business process (BPM). In a BizTalk environment messages are picked up by adapters and put through a robust message infrastructure where an orchestration engine allows you to implement your business processes. Along the way – a message takes – there are several points where performance of the overall message processing can be negatively impacted and therefore impacts your business.
