Every Linux VPS Server has its own limit when it comes to the system resources. It is somewhat limited to about 1GB of RAM. Clients always want their VPS (Virtual Private Servers) to be fast and much responsive as possible. Below are some quick tips to make the Linux VPS Servers work effectively.
Configuring MySQL cache sizes properly is one the common ways to expand the available RAM. If you noticed that your MySQL server instance is using too much memory, you can decrease the MYSQLcache sizes. And if its getting slower due to larger requests you can you can increase the chache size as per your needs.
One more way to increase the performance of the Linux VPS is to disable the control panels. Everyone likes to use the most popular control panels such as Cpanel & Plesk. But if you want to free your resources you should only use the control panels when necessary. You can install them again by running a small PHP script or using shell prompt. This will free up about 120MB of RAM.
Disable the unwanted features, modules and plug-ins such as Apache that are enabled in software packages. By disabling unnecessary modules or plugins will decrease the system memory that server softwares such as Apache requires, which will provide you more resources for the software that are more in need.
One of the top way to make your Linux VPS responsive is to disable the system services that are unnecessarily in use. The services which are not used not only consumes RAM and CPU space but they also make your server unsecured.
Apache server is a well-known for its role in the development of the World Wide Web and never been confusing to the clients. To free up the memory as per the needs check the memory apache is using and adjust the Startservers.
