Linux Performance: Almost Always Add Swap. Part 2: ZRAM

Originally published at: Linux Performance: Almost Always Add Swap. Part 2: ZRAM

Previously, we looked at how swap space, particularly swapping, can severely slow down Linux performance. We then tweaked Linux kernel parameters to make better use of server memory and to avoid heavy swapping. That article created some debate and good arguments for and against swap space. For example, if you have more than enough memory…
