What can become a reason of high load on Germany VPS server

Often there are situations when, after placing the project on the Germany VPS server, over time the pages begin to load very slowly. In such cases, you should check what causes the load on your server. Why load may arise:

- increase in the number of visitors. This factor is very pleasant for the owner of the site and this is not surprising, especially if your site has a commercial or informational direction;

- poorly optimized software. All services, services and utilities should be properly configured so that the resources of your server are not wasted;

- actions of hackers, including DDos-attack.

Increasing the number of visitors to the site can also trigger a load on the site. This may be due to the growing popularity of the resource. You can view attendance using special web tools directly in the browser, or by reviewing the logs in more detail. But the cause of increased attendance can also be the work of search engine bots. This can be traced in the server logs. To avoid this problem in the settings of robots.txt or .htaccess, you can restrict access to some bots.

Incorrect work of scripts is another significant reason for increased server load. This can be recognized using Apache web server modules. In order to eliminate the problem of increased load, which is associated with the work of scripts, their functioning must be adjusted. To perform tracing use extensions: xdebug or xhprof. Be sure to contact the developer.

Possible load on the processor from MySQL. The problem may lie in indexes or tables. In this case, also use the logs to identify errors.

The load on the VPS may come from the mail server. We are talking about spamming. If you do not do this intentionally, then it makes malicious code of attackers who hacked your server and send unwanted emails. Therefore, be sure to check that VPS mail server setup.

Load from DNS server. This can happen as a result of attacks on your site. To avoid this problem in the settings of the DNS server among the addresses that have access, specify only reliable IP.

But in addition to the reasons described above, others are possible, and most often they are a consequence of the actions of intruders. Therefore, always take care of the security of your accounts, change passwords in time and in case of any suspicion contact the technical support of the hosting provider.
