Tricky (?) questions about the LTM Web Acceleration
Here's some information I have;-
In 10.1 and beyond, ramcache has a "striped" cache, meaning that rather than each TMM having an independent cache, the TMMs collaborate to provide a unified cache with each TMM having a piece or "stripe" of the cache. The default split is 25% inter-stripe, 75% own.
http://support.f5.com/kb/en-us/solutions/public/11000/900/sol11990.html The RAM Cache feature introduces the new Ramcache.InterStripeCacheMemoryPercent database variable. This variable, set at 25 percent by default, defines what percent of the RAM Cache per TMM is reserved for local versions of cached objects.
The "remote hits" and "remote misses" statistics are used when a tmm receives a request for a cacheable object "owned" by another tmm. The first tmm may have a local copy of the object in its inter-strip cache - if it does not, it has to ask the other- or "remote" (in RAM Cache lingo) tmm. Hits and misses are self-explanatory.
The only use for this information I have found was to understand why eviction counts start when you reach 75% of your profile-assigned RAM Cache (as other 25% inter-stripe), although I'm sure F5 support have a use for it.
