 The HTTP2 specification mandates the use of TLS 1.2 or higher when TLS is used with HTTP2. It also places some additional constraints on the allowed ciphers in deployments to avoid known-problems as well as requiring SNI support. It is also expected that HTTP2 will be used in conjunction with proprietary transport security mechanisms about which the specification can make no meaningful recommendations.

+##### Connection Management
+###### GOAWAY Frame
 Sent by servers to clients to indicate that they will no longer accept any new streams on the associated connections. This frame includes the id of the last successfully accepted stream by the server. Clients should consider any stream initiated after the last successfully accepted stream as UNAVAILABLE and retry the call elsewhere. Clients are free to continue working with the already accepted streams until they complete or the connection is terminated.
 
 Servers should send GOAWAY before terminating a connection to reliably inform clients which work has been accepted by the server and is being executed.
 
-######PING Frame
+###### PING Frame
 Both clients and servers can send a PING frame that the peer must respond to by precisely echoing what they received. This is used to assert that the connection is still live as well as providing a means to estimate end-to-end latency. If a server initiated PING does not receive a response within the deadline expected by the runtime all outstanding calls on the server will be closed with a CANCELLED status. An expired client initiated PING will cause all calls to be closed with an UNAVAILABLE status. Note that the frequency of PINGs is highly dependent on the network environment, implementations are free to adjust PING frequency based on network and application requirements.
 
-######Connection failure
+###### Connection failure
 If a detectable connection failure occurs on the client all calls will be closed with an UNAVAILABLE status. For servers open calls will be closed with a CANCELLED status.

+# Overview of performance test suite, with steps for manual runs:
+
+For design of the tests, see
+http://www.grpc.io/docs/guides/benchmarking.html.
+
+## Pre-reqs for running these manually:
+In general the benchmark workers and driver build scripts expect
+[linux_performance_worker_init.sh](../../gce/linux_performance_worker_init.sh) to have been ran already.
+
+### To run benchmarks locally:
+* From the grpc repo root, start the
+[run_performance_tests.py](../run_performance_tests.py) runner script.
+
+### On remote machines, to start the driver and workers manually:
+The [run_performance_test.py](../run_performance_tests.py) top-level runner script can also
+be used with remote machines, but for e.g., profiling the server,
+it might be useful to run workers manually.
+
+1. You'll need a "driver" and separate "worker" machines.
+For example, you might use one GCE "driver" machine and 3 other
+GCE "worker" machines that are in the same zone.
+
+2. Connect to each worker machine and start up a benchmark worker with a "driver_port".
+  * For example, to start the grpc-go benchmark worker:
+  [grpc-go worker main.go](https://github.com/grpc/grpc-go/blob/master/benchmark/worker/main.go) --driver_port <driver_port>
+
+#### Comands to start workers in different languages:
+ * Note that these commands are what the top-level
+   [run_performance_test.py](../run_performance_tests.py) script uses to
+   build and run different workers through the
+   [build_performance.sh](./build_performance.sh) script and "run worker"
+   scripts (such as the [run_worker_java.sh](./run_worker_java.sh)).
+
+##### Running benchmark workers for C-core wrapped languages (C++, Python, C#, Node, Ruby):
+   * These are more simple since they all live in the main grpc repo.
+
+```
+$ cd <grpc_repo_root>
+$ tools/run_tests/performance/build_performance.sh
+$ tools/run_tests/performance/run_worker_<language>.sh
+```
+
+   * Note that there is one "run_worker" script per language, e.g.,
+     [run_worker_csharp.sh](./run_worker_csharp.sh) for c#.
+
+##### Running benchmark workers for gRPC-Java:
+   * You'll need the [grpc-java](https://github.com/grpc/grpc-java) repo.
+
+```
+$ cd <grpc-java-repo>
+$ ./gradlew -PskipCodegen=true :grpc-benchmarks:installDist
+$ benchmarks/build/install/grpc-benchmarks/bin/benchmark_worker --driver_port <driver_port>
+```
+
+##### Running benchmark workers for gRPC-Go:
+   * You'll need the [grpc-go repo](https://github.com/grpc/grpc-go)
+
+```
+$ cd <grpc-go-repo>/benchmark/worker && go install
+$ # if profiling, it might be helpful to turn off inlining by building with "-gcflags=-l"
+$ $GOPATH/bin/worker --driver_port <driver_port>
+```
+
+#### Build the driver:
+* Connect to the driver machine (if using a remote driver) and from the grpc repo root:
+```
+$ tools/run_tests/performance/build_performance.sh
+```
+
+#### Run the driver:
+1. Get the 'scenario_json' relevant for the scenario to run. Note that "scenario
+  json" configs are generated from [scenario_config.py](./scenario_config.py).
+  The [driver](../../../test/cpp/qps/qps_json_driver.cc) takes a list of these configs as a json string of the form: `{scenario: <json_list_of_scenarios> }`
+  in its `--scenarios_json` command argument.
+  One quick way to get a valid json string to pass to the driver is by running
+  the [run_performance_tests.py](./run_performance_tests.py) locally and copying the logged scenario json command arg.
+
+2. From the grpc repo root:
+
+* Set `QPS_WORKERS` environment variable to a comma separated list of worker
+machines. Note that the driver will start the "benchmark server" on the first
+entry in the list, and the rest will be told to run as clients against the
+benchmark server.
+
+Example running and profiling of go benchmark server:
+```
+$ export QPS_WORKERS=<host1>:<10000>,<host2>,10000,<host3>:10000
+$ bins/opt/qps_json_driver --scenario_json='<scenario_json_scenario_config_string>'
+```
+
+### Example profiling commands
+
+While running the benchmark, a profiler can be attached to the server.
+
+Example to count syscalls in grpc-go server during a benchmark:
+* Connect to server machine and run:
+```
+$ netstat -tulpn | grep <driver_port> # to get pid of worker
+$ perf stat -p <worker_pid> -e syscalls:sys_enter_write # stop after test complete
+```
+
+Example memory profile of grpc-go server, with `go tools pprof`:
+* After a run is done on the server, see its alloc profile with:
+```
+$ go tool pprof --text --alloc_space http://localhost:<pprof_port>/debug/heap
+```
