Ha, I used to call it bf in the code, but forgot to update the comment -- thanks.

Small comment issue but 👍 |
With this change, the generic batcher used by many inputs can now be buffered. Testing shows that this performance of the Graphite input by 10-100%, with the biggest improvements at lower numbers of connections.

Hello, Many thanks for this change and your continual improvements - every new version generally keeps getting better 👍 Have been running this version in our testing environment and it looks much, much better write performance to graphite plugin wise. We have not seen a client write failure since the upgrade and CPU usage of InfluxDB has dropped a bit on average as well. There is only one connection in to the influxdb graphite plugin.

With this change, the generic batcher used by many inputs can now be buffered. Testing shows that this improves performance of the Graphite input by 10-100%, with the biggest improvements at lower numbers of connections. Internal testing showed that this configuration -- a batcher per service, as opposed to per connection -- gave the best throughput and stable behaviour.
This patch also sets defaults for UDP input batching, which were not being set before.
