+#### concurrent_writes
+
+The number of concurrent write connections to use when writing to {{% product-name %}}.
+For optimal write performance, configure multiple concurrent writers.
+
+**Recommendation:** Set `concurrent_writes` to at least `2` in nearly all situations.
+For tuning, start with `min(number of CPU cores / 2, 10)`.

 ### Other Telegraf configuration options
 
+> [!Note]
+> Use the `influxdb_v2` output plugin (not the v1 plugin) for writing to {{% product-name %}}.
+> The v1 output plugin may work but is not recommended.

 For more plugin configuration options, see the
 [`influxdb_v2` output plugin README](/telegraf/v1/output-plugins/influxdb_v2/)
