+Optimize performance and system overhead when writing data to InfluxDB using some simple tips.
+
+_[Telegraf](/v2.0/write-data/use-telegraf/), [InfluxDB scrapers](/v2.0/write-data/scrape-data/),
+and many [InfluxDB client libraries](/v2.0/reference/client-libraries/) employ these optimizations by default._
+
+---
+
+## Batch writes
+Minimize network overhead when writing data to InfluxDB by writing data in batches.
+
+{{% note %}}
+The recommend batch size is 5000 lines of line protocol.
+{{% /note %}}
+
+## Sort tags by key
+Sort tags by key before writing data points to InfluxDB.
+_The sort should match results from the [Go `bytes.Compare` function](http://golang.org/pkg/bytes/#Compare)
+(lexicographic order)._
+
+```sh
+# Line protocol example with unsorted tags
+measurement,tagC=therefore,tagE=am,tagA=i,tagD=i,tagB=think fieldKey=fieldValue 1562020262
+
+# Optimized line protocol example with tags sorted by key
+measurement,tagA=i,tagB=think,tagC=therefore,tagD=i,tagE=am fieldKey=fieldValue 1562020262
+```
+
+## Use the coarsest time precision possible
+InfluxDB lets you write data with up to nanosecond precision.
+If data isn't collected at that precision, there is no need to write data at that precision.
+Use the coarsest precision possible for timestamps.
+This can result in significant compression improvements.
+
+_Specify timestamp precision when [writing to InfluxDB](/v2.0/write-data/#precision)._
+
+## Synchronize hosts with NTP
+Use the Network Time Protocol (NTP) to synchronize time between hosts.
+InfluxDB uses a host's local time in UTC to assign timestamps to data if no
+timestamp is included in the line protocol.
+If hosts' clocks aren't synchronized with NTP, the timestamps on data written
+to InfluxDB can be inaccurate.
