The collector can be a bottleneck, yes, but for this to happen it needs
to be in active use. So if the collector is always running but the
messages are being sent to syslog, no harm is done.
(A customer of ours found the hard way that the collector can block
backends when things are tight. They have since switched to syslog.)
