VPS hosting is the ideal choice for many businesses because of its high reliability and stability. With a VPS hosting service that includes all the resources, you can manage your website efficiently and provide a unique experience to your visitors. But when your business grows, your website experiences more traffic and requires more applications. Thus its performance gets slower, and it takes more time to load. In that case, you will need to consider adding more RAM and CPU to your VPS for optimal performance.
While some people think RAM is important and some other people think CPU is important, both of them are important for your server to ensure proper speed and performance. Here we are going to discuss the reasons why additional RAM and CPU are important.
What is RAM?
RAM or Random Access Memory is used for storing temporary data that need to be accessed by the CPU. All programs such as games, browsers, pictures, etc. load to the RAM from your storage space at startup. This allows the processor to access any data at any time randomly. Moreover, RAM is like a short term memory of the computer that allows the computer to get information quickly. Therefore, if numerous operations are happening in your VPS server, then you need more RAM to let it run optimally.
Why Do You Need Additional RAM?
As you know, RAM is essential for your VPS server. It can run your operations quickly with improved speed. So when your server doesn’t have enough RAM to run your website effectively, it can’t process the data according to visitors’ needs. Also, it will show “500 internal server error” to the visitors when they try to access your website. This will impact your business negatively and decrease your growth. Also, visitors may not visit your website after seeing this message. So if your business experiences high traffic, then you can add additional RAM to improve the performance.
If you have too little RAM, then your system won’t respond properly, and your server will go down. It will also start rebooting your system until the problem is solved. Therefore, you should have the right amount of RAM to deal with such problems. Usually, a server that contains Cpanel, Mail, MySQL, Statistics, firewall, webmails, 20 to 30 domains and experiences low to intermediate traffic will require 2 GB RAM for better performance.
In the same way, a server with 30 to 60 domains and intermediate to medium traffic requires 4 GB RAM to provide high stability and performance. The websites that meet thousands of traffic simultaneously will require 8 GB RAM for better results. This way, you can decide how much RAM your server needs to improve the performance of your websites.
What is the CPU?
CPU or processor is the Central Processing Unit of the server that processes the tasks. It usually works by executing the instructions fetching from memory and storing the results back in the memory. So if the CPU of your server is faster, then your website will be faster. Because the processor stores and retrieves the information in RAM, it should be able to handle the information faster. Even if you have sufficient RAM, your processing will be slower without a faster CPU.
Usually, your VPS server contains multiple CPUs and provides efficient performance by processing the data quickly. If the CPU is larger, then it can store more data and process them quicker. This way, the overall performance of your website depends on the CPU.
Why Do You Need Additional CPU?
CPU is important for your server to improve your website performance. If your VPS server has a small CPU, then it will get easily overloaded with multiple requests from the visitor. This will decrease your website speed and increase the content loading time when visitors try to access your page. Therefore, adding an additional CPU will be beneficial for you if your website experiences high traffic daily.
Usually, the size of the CPU your website needs depends on the load it takes. A 2-core CPU will work well with minimum loads. But for heavy loads, you can consider using 4 cores. Also, you can add more cores according to your website needs.
Conclusion:
RAM and CPU are the two major aspects of any server to provide appropriate speed and performance. With less amount of RAM, your websites will not work appropriately and show error messages to your visitors. Similarly, small CPUs get overloaded with many requests of visitors. Therefore, by adding additional RAM and CPU, you can let your visitors access your content seamlessly.
