+The following results were gathered on a :ref:`pmlogger farm<C.1 Centralized logging (pmlogger farm)>` deployment,
 with a default **pcp-zeroconf 5.3.2** installation (version 5.3.1-3 on RHEL), where each remote host is an identical container instance
 running `pmcd(1)`_ on a server with 64 CPU cores, 376 GB RAM and 1 disk attached (as mentioned above, 64 CPUs increases per-CPU metric volume).
 The key server is co-located on the same host as pmlogger and pmproxy, and ``proc`` metrics of remote nodes are *not* included.
