+## Tuning
+
+* No need in tuning for VictoriaLogs - it uses reasonable defaults for command-line flags, which are automatically adjusted for the available CPU and RAM resources.
+* No need in tuning for Operating System - VictoriaLogs is optimized for default OS settings.
+  The only option is increasing the limit on [the number of open files in the OS](https://medium.com/@muhammadtriwibowo/set-permanently-ulimit-n-open-files-in-ubuntu-4d61064429a).
+* The recommended filesystem is `ext4`, the recommended persistent storage is [persistent HDD-based disk on GCP](https://cloud.google.com/compute/docs/disks/#pdspecs),
+  since it is protected from hardware failures via internal replication and it can be [resized on the fly](https://cloud.google.com/compute/docs/disks/add-persistent-disk#resize_pd).
+  If you plan to store more than 1TB of data on `ext4` partition or plan extending it to more than 16TB,
+  then the following options are recommended to pass to `mkfs.ext4`:
+
+```sh
+mkfs.ext4 ... -O 64bit,huge_file,extent -T huge
+```
