## Improving NFS performance with GitLab
NFS performance with GitLab can in some cases be improved with
[direct Git access](gitaly/index.md#direct-access-to-git-in-gitlab) using
[Rugged](https://github.com/libgit2/rugged).
From GitLab 12.1, GitLab automatically detects if Rugged can and should be used per storage.
If you previously enabled Rugged using the feature flag and you want to use automatic detection instead,
you must unset the feature flag:
```shell
sudo gitlab-rake gitlab:features:unset_rugged
```
If the Rugged feature flag is explicitly set to either `true` or `false`, GitLab uses the value explicitly set.
From GitLab 12.7, Rugged is only automatically enabled for use with Puma
if the [Puma thread count is set to `1`](../install/requirements.md#puma-settings).
To use Rugged with a Puma thread count of more than `1`, enable Rugged using the [feature flag](../development/gitaly.md#legacy-rugged-code).
