Top 5 performance problems in .NET applications

144199_TN

.Net Framework is a popular software framework that is embedded with large class libraries.

Millions of users use this .Net framework platform, implemented by Microsoft for different kinds of Web Application development. It provides great support for a wide range of programming languages like C#, Asp.net, C++, Java, F#, J#, etc. Each language in the .Net framework has its own compiler.

.Net framework supports interoperability feature which means a code of one language can be used clearly with other languages in the same environment. It provides us the facility to build Windows Applications, Console applications, Client-Server applications, desktop applications, etc.

Let us discuss some performance problems in .Net applications:

There might be several factors like code-level errors, excessive exceptions logging, memory size issues, IIS server problems, etc. that make .Net applications run slower.

#1. Exception handling issues:

Exceptions should be handled and addressed properly by using throw, catch, and finally blocks. These handled exceptions are very helpful in coding as they show the way to identify the issues in the application. But if they are ignored and left unhandled, then it would make the code inefficient. Too many unhandled and hidden exceptions can severely hit the application performance and web page load-time.

Excessive loggings are also a major concern for .Net Applications. Though it might be a helpful tool while debugging the process to see the recorded abnormalities in the exception table. But if logging is made to catch exceptions at each tier of the project architecture, then it would result in the same exception log at – service, web, and data tiers. This increases the loading time unnecessarily.

#2. Garbage Collection Pauses:

In the .Net framework, the memory allocation and release process for the objects is managed by the Garbage collector. The GC is initialized when the allocated memory of the objects exceeds the configured limit given by the developer. At this instance the GC.Collect() method tries to retrieve the memory from the dead objects. This kind of frequent collection at the time of Generation 0 and Generation 2 heaps put lots of CPU load on CLR which eventually slows down the application process. Therefore, Garbage collection pauses also a factor for the slow processing of the application.

#3. IIS Server Bottlenecks:

IIS web server is the significant unit of the .Net framework. It is used in hosting web applications and websites that are developed using the .Net framework. It runs w3wp service to handle and respond to the incoming requests. In support of CLR, it also handles thread processing.
IIS can also be a factor responsible for slowing down the application performance in below ways:

  • Continuous utilization of resources like CPU, internal memory, etc. can cause server overload.
  • SSL certificates could have expired.
  • Increase in High CLR time.
  • Improper caching also affects performance.
  • Connection errors, Http errors, etc.

#4. Slow Database Calls:

Application performance issues could also be caused due to slow-running queries. As there is no contextual visibility about the SQL performance in making the app slower down, .Net developers often get blamed for slow down concern. Few other databases related reasons are like Ado.net with connectivity issues, improper formation of queries, poor schema, improper join operations, heavy usage of subqueries, cursor issues, improper conditional blocks, etc. In order to get rid of the slower processing issue, the team should distinguish code-level and query-level issues and analyze it.

#5. Synchronization and Locking issues:

Different kinds of synchronization strategies are offered by .Net framework such as locks, monitors, Reader locks, writer locks, mutex, etc.

Although these features help in making synchronization to your code for a particular purpose, still you might be left with a problem at a certain point. The problem could be as a portion of code that could only be executed through a single thread and until the first completes its process the other has to wait. In the practical world, this situation can be compared to a big mall with only one cashier inside. A huge number of people can enter and make shopping but at a certain point, all have to stop and stay in line at that only counter for payment. In this scenario, the shopping activity is nothing but multi threads and each person is represented as a thread. The payment activity is a single-threaded operation in which one person can pay for their products one at a time during his chance. Every thread has granted access permission one time and gets executed successfully.

But if a synchronized lock is created on a particular object then the thread must have to obtain the lock then only it will be allowed to execute that code. Until the first one is released the other thread have to wait for the execution in the queue. In this manner, there may be hundreds of threads generated during the project which eventually arises bottleneck issues. Thus, it indirectly affects the execution cycle and application performance.

It is, however, important to note that, though .Net Application has few performances related issues, still people never step back in using .Net framework and its latest versions for their successful project developments. After all, these are the factors that can also be found in other platforms as well.

.Net framework is one of the widely-used frameworks among reputed Asp.Net Web Development companies that offer Sky-high services to the global clientele with great security, efficiency, and reliability. To provide a great start for many Offshore businesses and fuel many startups, the .Net platform is the best.
