The importance of the processor and the CPU and its effect on the speed and performance of the site.
First, the Central Processing Unit is like the mind of the server or the mind of your site itself, and all operations are done by a method and it is the one that controls all parts of your site. In the field of hosting websites, the term processor or CPU means the number of processors available for your account and may reach up to 24 servers in some large dedicated servers.
Please note that in many cases the processor is referred to as “Core” and some companies specify for you a certain percentage of servers. The server that you can access because it is divided between all users according to their respective plans. Get every knowledge about Servers at VPS Server Host
CPU Processor Function
The wizard is responsible for carrying out the tasks and functions of the server, and these functions range from downloading data from the hard disk to the RAM, executing code or scripts, carrying out operations on databases, sending the website content to the visitor, and other operations. Hence, the wizard acts as the coordinator of the hosting resources.
The importance of the processor for hosting and when you need to increase the processor.
As I mentioned above, the wizard is very important to perform the tasks of hosting and coordination between “hardware” and various hosting resources. Therefore, the processor is important if your site uses databases and depends on a specific software script.
In all cases, increasing the number of processors or cores will lead to a clear improvement in the performance of your site, but there are some cases that require an increase in the processor capacity or the number of processors.
- Cases that require an increase in the processor capacity or the number of cores
- Too many visitors.
- Plugins that consume more resources, such as plugins and themes.
- The code was not updated or written incorrectly.
- The PHP setup is not optimized or not very good.
- The importance of RAM and its effect on website speed.
Firstly, the RAM, which is an abbreviation for Random Access Memory, and far from going into the reason for its name with this name is that the data in it can be accessed randomly, meaning that it has the ability to access any part of the data directly.
This is the reason for its high response speed and the speed of extracting the data stored on it, unlike the “Serial Access Memory” SAM, which requires that all data be passed from beginning to end if you want to reach a certain part of the data.
What is the function of the random memory in the server?
The RAM function in general is a temporary storage of data, and in order to explain to you in a simple way, when you open or run a program, the program files are copied from the hard disk to the RAM, and the wizard starts getting the program files from the RAM directly, and therefore the files are accessed very quickly compared to bringing them from Hard drive directly.
Perhaps the closest example of this is when you run many programs and large programs such as photo or video editing programs, then you will feel very slow in the speed of the device and stop it from working if these programs consume the RAM space and the device will not return to work normally only when there is space in the RAM either by closing some programs that work or increase the capacity of the RAM.
The importance of RAM for the site and its effect on its speed and performance
As I said earlier, the function of RAM is to store data, but now you can know the importance of the RAM and its effect on the speed of the site and its performance as it enables the processor of the server (the hosting server) to access the data faster and thus reduce the time the server needs to fetch your site data and send it to the user or The visitor.
Thus, increasing the RAM capacity for hosting leads directly to an increase in the speed of the site because the data that is fetched from the RAM is much faster than that which is brought from the hard disk. Perhaps one of the most common problems that may appear to you if the RAM capacity is less than what your site needs is:
- 500 Internal Server Error
- 503 Service Temporarily Unavailable Error
Often these errors appear when your site consumes the entire RAM and the most common is the first error that you encounter frequently when you visit many sites and if you send the support for hosting it will tell you that your site consumes the RAM allocated to it and that you need to increase the RAM of your site or upgrade the hosting (pay an additional cost).
But in order for me to be honest with you, the company wants to get the highest financial return and therefore it will advise you to upgrade the hosting plan, and you will find this error a lot if you are using poor shared hosting, but from personal experience, the cause of this error is in most cases a software error from one of the additions or Your site templates that consume a large area of RAM without the need for it, and while your purchase of additional space will lead to solving the problem, but you in fact dealt with the symptoms and not the disease itself and you pay for the additional RAM and you do not need it.
The effect of increased RAM capacity on site speed and performance
Increasing the RAM capacity leads to the following:
- The data that is fetched from the RAM is much faster than that which is downloaded from the disk itself.
- The increased RAM capacity ensures that the processor will not have to fetch data from the hard drive.
- Increasing the RAM capacity will make the programming languages that are written in the memory, the most famous of which is “PHP” to work very quickly and prevent errors.
- In general, increasing the capacity of the RAM will lead to an increase in the speed of the site, and it will enable it to carry out more and more complex tasks.
I/O input / output (Input/Output)
It is not a very important part in the field of hosting and will not significantly affect the work of the site, especially if your site does not depend much on databases or on broadcasting visual content.
In most cases, you will not notice that your site has stopped due to I/O capacity consumption, but you will only find a delay in the response because its function is the speed of transferring data from the hard disk to the RAM and therefore if your site consumes the capacity allocated to it, the time required to transfer data from disk to RAM will be long.
When do you need to increase I/O?
In short, if your site is very large and deals with a large number of database tables or depends on large databases, and also if your site depends on broadcasting visual content, then you will most likely need to increase the I/O capacity in order for your site to work very well. But most regular sites do not need to increase this source and therefore you will not find many hosting companies that are interested in displaying this part in the hosting features.
Disk capacity or hard disk storage space
Certainly, you know the importance of disk space, as it is the space in which your site files are hosted. Therefore, the more your site needs to store larger files, the more storage space you need. The type of disk itself is very important.
There are regular disks that are slow to respond, and there are solid state drives (SSDs) that are characterized by fast response and thus give your site’s speed a big boost and most hosting companies add an additional value if you want to use SSD disks.
How to choose a Dedicated Servers or a VPS?
Have you ever wondered how many Ways a Free VPS Can Endanger Your Privacy. If you want to buy a full server or VPS, there are some things that you should take into consideration.
RAM and processor capacity
The more powerful the processor, the more RAM needs to be increased in order for the system to be stable, and these are some of the common and preferred options:
- Number of Processors: 2, it is recommended that the RAM capacity be from 2 GB – 4 GB
- Number of Processors: 4, preferably 4 GB – 8 GB RAM
- Number of Processors: 8, it is recommended that the RAM capacity is 8 GB – 16 GB
- Number of processors: 16, it is recommended that the RAM capacity is 16 GB – 32 GB
- Number of processors: 24, it is recommended that the RAM capacity is 24 GB – 64 GB
In general, the higher the consumption of “bandwidth“, you must increase the capacity of the RAM. The higher the processor consumption, you must increase its power.
RAM capacity, system core and processor
If the number of processors is: 2 and the RAM capacity is less than 4 GB, it is recommended that the system core be 32bits.
If the number of processors is: 2 and the RAM capacity is 4 GB or more, it is recommended that the system core be 64bits.
If the number of processors is greater than 2 it is recommended that the system core be 64bits.
For your information, the cPanel and most other control panels currently work on 64bits systems.
The type of server operating system OS
It is always preferable to use Linux systems, especially distributions that are based on redhat, and the reason behind this is that these systems support all control panels and software that are used in the field of web hosting. There are also Debian systems, which sometimes outperform redhat systems in terms of stability and stability.
Summary: Hosting resources must be balanced!
After reading the article, you may go directly to increase the capacity of one of the hosting resources according to your need, and this is correct, but there is something that you must take into account which is the necessity of having harmony between the hosting resources, so you should not increase one of the resources at the expense of another source, such as double the RAM or Three times as much while the processor is weak, in which case your increase in RAM will be of no use or it will not give you the desired performance. But it is recommended that the more processor power, the more RAM is required, in order for your site to enjoy stability.
