Comment # 2 on bug 1067 from
attachment 327 [details] shows strace output of process pmdalinux when requesting the
following metrics over pmwebd, from a host with 25 interfaces (bridges, bonds).

network.interface.in.bytes,
network.interface.out.bytes,
network.interface.in.packets,
network.interface.out.packets

It takes more than 1 second to return a response, and pmwebd times out when
using the default time-out for PMCD_REQUEST in pmwebd.options of 1 second.
