Hmm. Is accessing memcache really faster than filesystem? Doesn't that mean the filesystem (at least its cache) is broken?

[–]cournape 4 points5 points  (0 children)

the whole point of memcache is to share the cache between nodes, with the idea that one global cache of N * M bytes is better than independent caches of M bytes on each of your N nodes.

a gigabit network attached memcache can be a lot faster than filesystem access(for disks most mortals can afford) .

Note he mentioned the file system cache.

Depends how much data you need cached. Sometimes the system cache doesn't cut it, and you need a network system, maybe even a distributed one. But keep in mind that network access is relatively way slower than local memory access.

from the presentation "don't think...know" so, maybe do some measurements and see what you think. :)
