To verify that the new parameter is enabled, you need to execute: sysctl -p # Or sysctl -a | grep vm.swappiness To configure swap, use the vm.swappiness parameter, the value of which must be entered or edited in the nf configuration file: nano /etc/nf # Add line vm.swappiness = 10 # The swap file is only activated if 10% of RAM is freeĪfter that, you need to save the file and reboot the system. Ubuntu by default unloads data when RAM is 40% full. It is also not recommended to use Swap on a server with SSDs – it significantly reduces the storage life (frequent write and read processes). The approach doesn’t make sense in systems with a large amount of RAM, especially since the RAM is faster than constant memory. Thus, you can use more RAM than there is in the system. To perform time-consuming tasks, is used virtual memory (swap) – when RAM is full, part of the program is transferred to the hard drive. ![]() If the file system is Ext3, then it is recommended to transfer it to Ext4 – a more productive and improved version. File systemįirst, make sure that you are using the ext4 file system: df -T # The output will be similar to: Filesystem Type 1K-blocks Used Available Use% Mounted on / dev / vda1 ext4 20511592 2494920 16960708 13% / tmpfs tmpfs 250152 0 250152 0% / dev / shm tmpfs tmpfs 50% / run / lock To get started, analyze the load on the server and test your website for the load. Do not rush to buy new hardware, maybe the main point is in software. ![]() Tuning system parameters is used to increase the responsiveness and performance of the server.
