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. |
