223 After adding the system wide name cache we reran ``ls \-l''
259 Statistics on the performance of both caches show that
260 the large performance improvement is
261 caused by the high hit ratio.
262 The name cache has a hit rate of 70%-80%;
263 the directory offset cache gets a hit rate of 5%-15%.
