- *`Transparent Hugepage Support`*: This is a Linux kernel feature intended to improve performance by making more efficient use of processor’s memory-mapping hardware. But this may cause [problems](https://blogs.oracle.com/linux/performance-issues-with-transparent-huge-pages-thp) for non-optimized applications. As most Linux distributions set it to `enabled=always` by default, we recommend changing this to `enabled=madvise`. This will allow applications optimized for transparent hugepages to obtain the performance benefits, while preventing the associated problems otherwise.
```sh
echo madvise | sudo tee /sys/kernel/mm/transparent_hugepage/enabled
```
Also, set `transparent_hugepage=madvise` on your kernel command line (e.g. in /etc/default/grub) to persistently set this value.
