# Introduction
|
|
|
|
[JetStream 2](https://browserbench.org/JetStream) is a JavaScript and WebAssembly benchmark suite focused on the most advanced web applications. It rewards browsers that start up quickly, execute code quickly, and run smoothly.

# Building
|
|
|
|
Please build iwasm and wamrc, refer to:
|
|
- [Build iwasm on Linux](../../../doc/build_wamr.md#linux), or [Build iwasm on MacOS](../../../doc/build_wamr.md#macos)
|
|
- [Build wamrc AOT compiler](../../../README.md#build-wamrc-aot-compiler)
|
|
|
|
And install emsdk, refer to [the guide](https://emscripten.org/docs/getting_started/downloads.html). Don't forget to activate
|
|
emsdk and set up environment variables. For example, use instructions below to install it under /opt and activate it:
|
|
``` bash
|
|
$ cd /opt
|
|
$ git clone https://github.com/emscripten-core/emsdk.git
|
|
$ cd emsdk
|
|
$ git pull
|
|
$ ./emsdk install latest
|
|
$ ./emsdk activate latest
|
|
$ echo "source /opt/emsdk/emsdk_env.sh" >> "${HOME}"/.bashrc
|
|
```
|
|
|
|
And then run `./build.sh` to build the source code, the folder `out` will be created and files will be generated under it.
|
|
|
|
# Running
|
|
|
|
Run `./run_aot.sh` to test the benchmark, the native mode and iwasm aot mode will be tested for each workload, and the file `report.txt` will be generated.
|
|
|
|
Run `./test_pgo.sh` to test the benchmark with AOT static PGO (Profile-Guided Optimization) enabled, please refer [here](../README.md#install-llvm-profdata) to install tool `llvm-profdata` and build `iwasm` with `cmake -DWAMR_BUILD_STATIC_PGO=1`.
|
|
|
|
- For Linux, build `iwasm` with `cmake -DWAMR_BUILD_STATIC_PGO=1`, then run `./test_pgo.sh` to test the benchmark with AOT static PGO (Profile-Guided Optimization) enabled.
|
|
|
|
- For Linux-sgx, similarly, build `iwasm` with `cmake -DWAMR_BUILD_STATIC_PGO=1`, then `make` in the directory `enclave-sample`. And run `./test_pgo.sh --sgx` to test the benchmark.
