[mod.computers.vax] directory cache hit rate

sasaki@HARVARD.HARVARD.EDU (Marty Sasaki) (10/21/86)

One of o~rur 8}i650's has been having poor i/o performance. Quick analysis
has shown that the directory hit rate has consistantly been between 0
and 20%, and this is with a 1024 page directory cache. Any ideas?
