+# Benchmarks
+
+Benchmarks are based on [JMH](http://openjdk.java.net/projects/code-tools/jmh/).
+
+# Running Benchmarks
+
+Running benchmarks is disabled by default and can be activated via the `benchmarks` profile.
+To run the benchmarks with default settings use.
+
+```bash
+mvn -P benchmarks clean test
+```
+
+A basic report will be printed to the CLI.
+
+```bash
+# Run complete. Total time: 00:00:15
+
+Benchmark                                    Mode  Cnt        Score       Error  Units
+MappingMongoConverterBenchmark.readObject   thrpt   10  1920157,631 ± 64310,809  ops/s
+MappingMongoConverterBenchmark.writeObject  thrpt   10   782732,857 ± 53804,130  ops/s
+```
+
+## Running all Benchmarks of a specific class
+
+To run all Benchmarks of a specific class, just provide its simple class name via the `benchmark` command line argument.
+
+```bash
+mvn -P benchmarks clean test -D benchmark=MappingMongoConverterBenchmark
+```
+
+## Running a single Benchmark
+
+To run a single Benchmark provide its containing class simple name followed by `#` and the method name via the `benchmark` command line argument.
+
+```bash
+mvn -P benchmarks clean test -D benchmark=MappingMongoConverterBenchmark#readObjectWith2Properties
+```
+
+# Saving Benchmark Results
+
+A detailed benchmark report is stored in JSON format in the `/target/reports/performance` directory.
+To store the report in a different location use the `benchmarkReportDir` command line argument.
+
+## MongoDB
+
+Results can be directly piped to MongoDB by providing a valid [Connection String](https://docs.mongodb.com/manual/reference/connection-string/) via the `publishTo` command line argument.
+
+```bash
+mvn -P benchmarks clean test -D publishTo=mongodb://127.0.0.1:27017
+```
+
+NOTE: If the uri does not explicitly define a database the default `spring-data-mongodb-benchmarks` is used. 
+
+## HTTP Endpoint
+
+The benchmark report can also be posted as `application/json` to an HTTP Endpoint by providing a valid URl via the `publishTo` command line argument.
+
+```bash
+mvn -P benchmarks clean test -D publishTo=http://127.0.0.1:8080/capture-benchmarks
+```
+
+# Customizing Benchmarks
+
+Following options can be set via command line.
+
+Option | Default Value
+--- | ---
+warmupIterations | 10
+warmupTime | 1 (seconds)
+measurementIterations | 10
+measurementTime | 1 (seconds)
+forks | 1
+benchmarkReportDir | /target/reports/performance (always relative to project root dir)
+benchmark | .* (single benchmark via `classname#benchmark`)
+publishTo | \[not set\] (mongodb-uri or http-endpoint)

-# MongoDB Log4J Appender
-
-This module sets up a Log4J appender that puts logging events in MongoDB. It is fully configurable
-and connects directly to the MongoDB server using the driver. It has no dependency on any Spring package.
-
-To use it, configure a host, port, (optionally) applicationId, and database property in your Log4J configuration:
-
-    log4j.appender.stdout=org.springframework.data.mongodb.log4j.MongoLog4jAppender
-    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
-    log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n
-    log4j.appender.stdout.host = localhost
-    log4j.appender.stdout.port = 27017
-    log4j.appender.stdout.database = logs
-    log4j.appender.stdout.collectionPattern = %c
-    log4j.appender.stdout.applicationId = my.application
-    log4j.appender.stdout.warnOrHigherWriteConcern = FSYNC_SAFE
-
-It will even support properties in your MDC (so long as they're Strings or support .toString()).
-
-The collection name is configurable as well. If you don't specify anything, it will use the Category name.
-If you want to specify a collection name, you can give it a Log4J pattern layout format string which will have
-the following additional MDC variables in the context when the collection name is rendered:
-
-    "year" = Calendar.YEAR
-    "month" = Calendar.MONTH + 1
-    "day" = Calendar.DAY_OF_MONTH
-    "hour" = Calendar.HOUR_OF_DAY
-    "applicationId" = configured applicationId
-
-An example log entry might look like:
-
-    {
-      "_id" : ObjectId("4d89341a8ef397e06940d5cd"),
-      "applicationId" : "my.application",
-      "name" : "org.springframework.data.mongodb.log4j.MongoLog4jAppenderIntegrationTests",
-      "level" : "DEBUG",
-      "timestamp" : ISODate("2011-03-23T16:53:46.778Z"),
-      "properties" : {
-        "property" : "one"
-      },
-      "message" : "DEBUG message"
-    }
-
-To set WriteConcern levels for WARN or higher messages, set warnOrHigherWriteConcern to one of the following:
-
-* FSYNC_SAFE
-* NONE
-* NORMAL
-* REPLICAS_SAFE
-* SAFE
