Show the cache hit ratio at
the server console
This is the number of cache hits
divided by the number of attempts to
get a file cache buffer from the cache.
Any amount above 90 percent is good.
This means the system is spending
less time going to the disk to retrieve
data. Lower numbers indicate NSS
needs more memory. If this occurs,
you might want to set the cache
balance percentage higher.
Cache hit is the number of times that
NSS finds the desired file block in the
cache buffers.
Cache miss is the number of times that
NSS does not find the desired block in
the cache buffers.
If you allocate more memory to NSS,
the cache hit percentage increases.
You can add more memory by adding
more physical memory, increasing the
cache balance, or increasing the
minimum number of cache buffers for
NSS. We do not recommend lowering
the minimum number of OS cache
buffers.
nss/CacheHit
Set the number of
Authorization cache entries
This parameter specifies the number
of cache buffers that will be used to
speed up authorization requests. If
many trustees have been set on
different files and directories, we
recommend that you increase this
number. The default is 1024. The
range is 16 to 50000.
