For Linux NFS service, it's a option in /etc/exports. The default for "modern" (post-1.0.1) NFS utilities is "sync", which means that data and metadata will be written to the disk whenever NFS requires it (generally upon an NFS COMMIT operation). This is the same as Solaris with UFS, or with ZFS+ZIL. This works with XFS, EXT3, and any other file system with a working fsync().
It's possible to switch this off on Linux, but not recommended, as there is a chance that data could be lost if the server crashed. (For the same reason, the ZIL should not be disabled on a Solaris NFS server.)
