With it running, NFS (and AFS) mounts that use the <code>fsc</code> mount option keep a copy of the data they read on local disk, so the second read of a file comes from the cache instead of the network. Setup is four steps: install the package, enable it (on Debian and Ubuntu that means <code>RUN=yes</code>), start the daemon, and remount the NFS share with <code>fsc</code>. This guide shows each step on Ubuntu 24.04 and 26.04, how to prove the cache is in use, and when it does not help.</p>
