Change subject: Restore mc1007 memcached growth factor to 1.05 as the rest of
the cluster.
......................................................................
Restore mc1007 memcached growth factor to 1.05 as the rest of the cluster.
Memcached on mc1007 has been running with growth factor 1.15 for a while
to test differences between 1.4.21 and 1.4.25 (the latter requiring 1.15
to work properly). mc1007 shows a stunning hit rate but we don't have
precise metrics of what it was before the 1.15 value change, since we
enabled diamond/graphite only afterwards. I want to double check if this
great performance is due to a lucky shard or if the growth factor is
playing a role. In any case, mc1007 will be restore to the current
default value of the cluster (1.05).
