Question #170630 on Graphite changed:
https://answers.launchpad.net/graphite/+question/170630

chrismd proposed the following answer:
The only way I can imagine memcache slowing you down is if the
MEMCACHE_HOSTS setting is not identical on all webapps and/or not all
the memcaches are running. These problems could cause more cache misses.
The order of this list only matters in that it has to be the same on all
servers.

You do not need to distribute data across all memcaches but doing so
improves the cache hit rate. If server1 gets a request and caches it,
then server2 gets the same request, it will only have a cache hit if the
memcache configuration is cluster-wide rather than machine-local.
