# 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 |
||||
``` |
||||
