Does swap File improve performance?

The short answer is, No. There are performance benefits when swap space is enabled, even when you have more than enough ram. Update, also see Part 2: Linux Performance: Almost Always Add Swap (ZRAM). …so in this case, as in many, swap usage is not hurting Linux server performance.

How to extend an LVM swap partition in Linux?

1. Verify availability of the new space. # fdisk -l /dev/sda Disk /dev/sda: 4294 MB, 4294967296 bytes, 8388608 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 byte 2. Create additional partition for the new swap partition.

How do I increase swap volume in Linux?

The following solution will first add a new physical volume (PV) to the volume group being used, and will then extend the swap logical volume. In the example below, the voljume group is called vg_main, the swap logical volume is called lv_swap, and the new physical volume is called /dev/xvdd.

How can I increase the size of my swap partition?

Do not disable swap on a production server while it is under heavy load, and is using the swap excessively! In such a scenario add another swap partition instead. To increase the size of the swap we extend the logical volume holding it. In this example with one more Gigabyte:
