Reduce the size of the NFS client code by omitting code that's only required
for NFSv3 and NQNFS support, leaving only that code required to use NFSv2
servers.
.It Cd options SOFTDEP
Enable kernel support for soft-dependencies in FFS filesystems.
Softdep improves write performance by aggregating and properly
ordering disk metadata writes, achieving near-asynchronous write
performance while maintaining the filesystem consistency of
synchronous writes.
Soft-dependencies are enabled on a per-mount basis.

for large directories.
