Slow Application? Here’s What to Do
Today, everything we work on relies on being connected to an app. Whether we are in a household or running a business, applications have become as accessible as air. Alright, almost like air. If your business relies on applications to survive, a Slow Application spells disaster. Getting to the bottom of the slowdown becomes a tedious exercise of pointing fingers and going down the rabbit hole. Even worse is if it affects a business’ customers.
The slowdown creates a bottleneck in your business operations and ultimately leads to massive problems if left unchecked for too long. Today, everyone lives a fast-paced life, and the last thing anyone wants is something that slows them down. So, if your application is slowing down your business, you lose productivity and make an end user’s experience miserable. It leads to irate customers or customers who instantly decide to switch to competition, which ultimately leads to a loss of revenue. Nobody wants to end up there.
So, what do we do? Firstly, getting to the bottom of what is causing your applications to slow down is imperative. Getting to the source will always provide a clearer picture. There are steps to take to diagnose and troubleshoot the issue. You need to know when there is an issue slowing your application down. You can add an extra layer of protection by employing a tool to support you in monitoring your application performance.
What Causes Slow Applications?
There are many reasons an application can slow down. Some of the most common reasons are as follows:
- An overloaded server
- Poorly written out database requests
- Requests that take too much time to execute
- Web requests are slow
- Configuration issues because of DNS
- Problems with the network performance
- Hardware failure
- Application code executed slowly
Understanding the causes of a slow application allows you to be forward-thinking regarding debugging and troubleshooting. If you know that these possible issues can arise, you can tackle them before deploying your application or know what needs to be done to fix them when the application deploys. Knowing these potential causes gives you a sense of direction, but when the issue is more complicated and affects different areas, it makes manual debugging a tough job. However, if you know that there is an issue, here are some steps you can take to face it.
Steps to Take If You Face an Application Slowdown
When an application starts to slow down, it sends the developing team into a frenzy. There is an urgency to get to the bottom of it. The point of this exercise is to ensure that the application’s end-user has the best Here are some of the steps you can take if you are facing an application slowdown:
What kind of a slowdown is it?
A slowdown can be of two types which are easily categorized based on the frequency of the occurrence of the slowdown:
The application slowdown’s frequency can affect the way an end-user behaves. For instance, if the error is one-time, it is more than likely that the user will contact the developers. They can start reaching out to the customer support team through avenues such as live chat, social media direct messages, and emails. Most of the time, the user can also solve the issue themselves. Solutions can be found via the application documentation available on your website. On the other hand, if the problem is recurring, the user would most likely quit using your application altogether.
You must be wondering why this matters? Well, if an error is a one-time error, it’s usually an easy fix. However, if it has a history - and has been recurring - then it means that the error has more complex and serious repercussions requiring you to speak to specific teams to tackle the issue.
Is the server performing optimally?
Check if the server is working the way it should. Applications depend on these servers, and they are the most notorious reason why applications slow down. Today’s application architectures deploy on a multi-layered network of servers. This increases the complexity of the issue, making it imperative for you to have clear network visibility. The application’s speed can be caused by the server’s performance issues, lack of RAM, and an overload on DNS, AD, or LDAP servers.
To deal with this issue, you must outline all your dependencies. In the case of a server performance issue, it is affected by an external problem because it is an external dependency. Start with creating an outline of the dependencies of your system. By outlining what your application's health relies on, you are essentially mapping out the influences of your applications. Here you list what happens to your application if a certain factor is altered and what happens if something goes wrong.
The method, namely, Application Dependency Mapping, creates a sense of understanding for the developing team to see all that affects the external application, such as storage, servers, and networks. Here you are looking for their interactions: understanding how the individual components make the application work. By doing this, you will be able to tell whether the application will work properly or not.
Is the client’s system causing the issue?
Sometimes, app performances can slow down at the client’s end, and it may not be your fault at all. These are difficult to diagnose because the problems are not in your system. There can be a few reasons for this to happen, for example:
- The end-user system may be outdated. Sometimes customers may have old hardware causing issues like lack of memory, an older version of a local disk storage system, or a slow CPU.
- The application requires a lot of CPU capabilities from the client-side, and it may be that the client does not have the right amount of memory that your application needs.
- Sometimes, the application performs slowly because there is resource competition. The end-user’s hardware may have an abundance of programs competing for memory, CPU, and other resources.
When you are sure that the system environment is working the way it should, try helping the customer out by getting access to their systems. It gives you a much clearer picture, providing them with information on what they can do to improve their experience.
Do you have a robust knowledge base?
A knowledge base essentially has strong documentation in place. Consider this documentation as a virtual manual that a user can access. A lot of times, application slowness can be solved with a quick fix. For this, you require a certain level of foresight. A robust knowledge base provides comprehensive information about your application. It acts as a self-help guide to your users, coming in handy when the issue is coming from the user-end.
Do you have an APM tool?
There’s only so much vigilance you and your team can ensure. At the end of the day, you are human and will need a break, and you have a life. Consider employing the help of an application performance monitoring or APM tool. Most APMs support developers in monitoring the system and ensuring to let you know where and when there is an issue. You can try out free ones, but soon you might want to invest in one that can give you better features. It’s good to explore this option because it allows you to have peace of mind. It takes away the time you spend on debugging so that you can redirect all your focus on making your best application with newer developments.
