10 ASP.NET Performance and Scalability Secrets

There are numerous ways in which the performance and scalability of ASP.NET 2.0 can be boosted. These techniques are often regarded as secrets in ASP.NET 2.0. For instance, the bottlenecks in the Membership and Profile provider can be solved to ensure faster authorization as well as authentication. Similarly, the Page fragment caching on the browser allows in saving the amount of time required in downloading on repeated visits. Similar other tactics can be implemented to increase the performance of this web application framework.

Here is an overview of some of these secrets:

1. ASP.NET Pipeline Optimization

asp.net application developmentQuite a few number of the application framework’s default HttpModules are placed on the request pipeline, intercepting every request. Now, all the modules such as the SessionStateModule and the HttpContext are not always necessary. For instance, one does not need to use the WindowsAuthentication if the same is not being used for the users. Pipeline optimization helps in scalability to a significant extent.

2. ASP.NET Process Configuration Optimization

The application’s Process Model configuration defines process level properties such as the numbers of threads used by the application or the way it blocks a thread etc. The limited number of defaults in several cases and the easy availability of hardware and dual core with gigabyte RAM servers becoming a popular choice make it necessary to tweaked the process model configuration to make the application consume more resources and hence, lead to better scalability.

3. Factors to Consider before Going Alive

A little tweaking on the web.config in the event of using the applications’ Membership Provider is necessary prior to going live on the production server. Adding applicationname attribute in Profile Provider is necessary. The profile provider automatically saves the profile with the completion of the page requests. Finally, the role manager queries the database with the intention of getting the user roles.

4. Content Delivery Network

The requests from the browsers reach the server by means of the Internet backbones spanning the world. The longer the distance that has to be covered, the slower is the pace. On the other hand, setting up a server in the respective locations and then redirecting the users to this particular server paves the way for lower network latency and faster data transfer rate. Performance automatically improves as a result.

5. Caching AJAX Calls on Browser

Caching the state of the user to enable the user visit on the following day implies promising them with a cached page, which loads immediately from the browser cache and not the server. This allows faster loading for the second time and as the user repeats his action, a cached result comes up from the local cache and reduces the time for network roundup. A fast loading, responsive site is created with the speed increased to a great extent as well.

6. Deriving the Best Out of the Browser Cache

This can be done in the following ways:

  • Making consistent use of the URLs
  • Caching the static content for an extended period
  • Making use of a cache friendly folder structure
  • Reusing the common graphic files
  • Changing the file names at the time of expiring the cache

7. On Demand UI Loading for Better Experience

The help section can be loaded by striking at help.aspx and injecting its response inside the HelpDiv. With this method, the UI can be broken into the smaller .aspx files, which contains good amounts of HTML that has to be shown on the UI on-demand. Consequently, the download can be kept to the minimum for loading the basic stuff.

8. Optimizing the Application’s Profile Provider

It is a secret to many that there are two significant stored procedures in ASP.NET 2.0 Profile Provider that can be optimized properly. Using them without optimization actually makes the server sink and let your business go down with heavy load.

9. Enquiring the Membership Tables without Affecting the Site

Queries directed to the Membership Tables have always led to the taking away of all the power of the CPU as well as the HDD, due to which the site becomes slow and also non- responsive at times. Learning the way of questioning without the obvious negative consequence ensures boosting the performance of ASP.NET to a great extent.

10. Prevention of Denial of Service Attack

Prevention of the Denial of Service or DOS attack is necessary to save the web services from becoming the target for hackers. IsValid, which comes up as a static method, does the checking. There are also few websites that take precautions beforehand for the application level DOS attacks.

These are some of the tricks cum strategies to enable ASP.NET deliver faster and better performance. The best part is that with these methods, the hardware configuration remains the same.

A Tester’s perspective on agile Software testing projects

Agile no longer seems to be unfamiliar to the industry. Over the years, the software has progressed rapidly and has developed to a commonly accepted methodology. Conducting tests in Agile projects has necessitated a tester to undertake a paradigm shift from conventional testing roles. It requires a change in the attitude where a tester needs to take up a more involved and upfront role against the traditional relay race oriented approach. This particular software strives towards getting things right and in place in the very first attempt thereby, reducing the need for QA testers to receive something over the finish line.

Agile is a methodology that aims towards delivering constant value to users /customers frequently and incrementally based on the feedback and communication. These two aspects are important to successful Agile method and testers need to play an important role for generating value in such projects through different iteration phase.

Software testing servicesUsually, the QA activities involve three phases in terms of a project type. However, it is to be noted that there is no set or predefined rule that guides the process and it can mould itself according to the project situation. The role of an Agile QA tester is not restricted to a set process as the methodology directs role in accordance to the situation.

Pre-iteration: This particular phase involves a detailed analysis of the requirements by the BAS following a detailing of the acceptance criteria for that specific story. Since the QA testers seem to be an instantaneous consumer of the requirements, it becomes significant to verify the requirements quite often and early.

Verification of the requirement/story: Agile testing involves early feedback, which might not always be offered by testing the requirements, but at times by conducting early requirement testing. The QA testers need to have a clear look at the requirements for maintaining testability and clarity effectively. This helps determining the requirements that are testable and definite.

  • Requirement should always be small for it should match sense with the context.
  • Acceptance criteria should never be duplicate or overlap from different stories.

To ensure doing this successfully, it is important to achieve a strong communication between the Business Analysts/Development/ Quality Assurance.

Testable: The testability aspect necessitates a complete scan of the story to determine what needs to be done for testing the same. The factors include:

  • Test data
  • Environment
  • Dependency on other requirements
  • Finding requirements that are hidden

Getting information about all these details early makes way for prioritizing the story in accordance to the backlog thereby, enabling a smooth execution in the iteration phase. QA testers also take part in meetings related to iteration planning for offering a perspective enabling the team to produce a developer estimate. This participation is deemed as a big role as the professionals do escalate some implicit requirement.

Activities of the QA in the Iteration Phase
Once the QA testers seem to be happy with the acceptance criteria, they help defining the acceptance tests for that particular story. What are acceptance tests? Well, these are actually requirements in aspect of the tests that can be executed to understand the expectations from the requirements. These usually tend to be automated and help driving development. It is important to note that these should not involve too many scenarios of corner case as it would lead to unnecessary delays and might end up producing likewise automated tests.

People often fail understanding the fact that acceptance tests in terms of Agile projects are different from the conventional and traditional projects. Acceptance testing in such projects are conducted prior to delivering the software as against to the traditional projects, which involve performing tests at the software lifecycle end.

Purposeful Use of Automation
Automation in Agile can turn out to be quite controversial. Many people make the mistake of attempting to automate everything and end up being caught in a trap of long cycle feedback. Automation is all about providing feedback early in terms of the latest code alongside being the key to identifying what is worth and what is not.

Each automated test involves a cost associated with the same. The automation cost must always be compared to the cost of operating or running the test. The questions that should be asked in such situations are:

  • What to do in case it is not an automated test?
  • What can get lost and what would exactly be the cost of setting up things around the code that is responsible for the coverage loss?
  • Is manual testing cheaper?

Well, the answers to the questions might not always be straightforward in terms of finding the test value. It often ends up to be a contextual decision depending on the project size and the number of people engaged with the same. Alternatively, a lengthy feedback cycle equals more people contributing time for getting the instant feedback.
