MetaData Cache displays the number of hits and misses in the Metadata cache.Hits are satisfied from the cache, which is in physical memory. Misses are satisfied by loading the appropriate blocks from disk into the cache. AdvFS volumes make no contribution to these numbers.
UBC Cache displays the number of hits and misses in the UBC. Hits are satisfied from the UBC , which is in physical memory. Misses are satisfied by loading the appropriate blocks from disk into the UBC. Prior to this version of " vmubc " only the UBC data
cache was counted.
This is the diffrences between MetaData cache and UBC Cache. Im not sure if both chache hits can be found in HP-UX, might someone assist you in this.

could any one point out any open source test-suites for "File cache" testing and as well as performance test suites for the same. Currently my system is up with Linux/ext4.

NAME
cachefsstat - Cache File System statistics
SYNOPSIS
path... ]
DESCRIPTION
The command displays statistical information about the cache filesystem mounted on path. The statistical information includes cache hits
and misses, consistency checking, and modification operations. If path is not specified, all mounted cache filesystems are used. can also
be used to reinitialize this information (see description for the option). The statistical information has the following format:
<cache hit rate>
<consistency checks>
<modifies>
where each of the above is defined as:
cache hit rate
The percentage of cache hits over the total number of attempts followed by the actual numbers of hits and misses.
consistency checks
The number of consistency checks performed followed by the number that passed and the number that failed.
modifies The number of modify operations, including writes, creates, and so on.
Options
recognizes the following option:
Zero (reinitialize) statistics.
Execute before executing again to gather statistics on the cache performance. This option can only be used by the supe-
ruser. The statistics printed reflect those just before the statistics are reinitialized.
RETURN VALUE
returns the following values:
Success.
non-zero An error occurred.
