Reasons for heavy load on a VPS or dedicated server

1. VDS (Virtual Dedicated Server) or VPS (Virtual Private Server) is a hosting service where the user is provided with a virtual server with maximum privileges. VDS or VPS emulates the operation of a real physical server — there is root access, you can install your own operating systems and software. There are usually several independent virtual servers running on a single physical server. How do I evaluate the server load? To find out how loaded the server is on the Linux operating system, use the average load value — load average. It shows how many processes are currently in the queue to be executed. At high rates, processes that are in the queue must wait until others run out to free up hosting resources. This means that the running time of certain processes becomes too long. As a result, with a high load on the server in Linux, it turns out that too many processes accumulate in the queue and the site may stop processing them altogether.

The three values in the load average show how many processes on average are waiting for execution in time intervals: one, five, and fifteen minutes. In theory, it would be good if this value did not exceed the number of cores of your processor. As a rule, when hosting Wordpress Hosting on a dedicated server, the user rarely gets more than one core. For this reason, the load average should not exceed a value of 1-1.5, otherwise delays may occur. Since a single core cannot execute more than one process at a time, and its scheduler tries to allocate resources so that there are enough resources for each process. And, better not to forget about $1 Hosting Canada to host your website. Also, some processes are necessarily in standby mode. When considering a single-core processor, we can say that: -if the load average is less than one – there is no load; -with an average load from 1 to 3, the load is there, but it is considered normal; -with an average load of 3 to 10-a strong server load, you should think about finding the cause and its solution; -with an average load of more than 10-overload, you need to solve the problem; -with an average load of more than 20 – it is difficult to get a response from the server due to heavy lags. To recalculate these numbers for processors with a different number of cores, simply multiply them by the number of cores. If you need to know the current average load value, type the top command.

What causes a large load on the server Why there is a high load: • high CPU usage; • insufficient amount of server RAM; • too high a load on the drive; • high load on the network port; If you want to find out how loaded your CPU, RAM, or server disk is, you need to use the "top" command. It shows
