## FastDeploy 服务化性能压测工具(PaddleOCR-VL)
|
||
|
||
本文档主要介绍如何对 [PaddleOCR-VL](https://www.paddleocr.ai/latest/version3.x/pipeline_usage/PaddleOCR-VL.html) 进行性能测试。
|
||
|
||
### 数据集:
|
||
|
||
下载数据集到本地用于性能测试:
|
||
|
||
<table>
|
||
<thead>
|
||
<tr>
|
||
<th>数据集</th>
|
||
<th>获取地址</th>
|
||
</tr>
|
||
</thead>
|
||
<tbody>
|
||
<tr>
|
||
<td>OmniDocBench v1 数据集,共 981 个 pdf 文件</td>
|
||
<td><code>https://github.com/opendatalab/OmniDocBench</code></td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
|
||
### 使用方式
|
||
|
||
1. 启动 FastDeploy 服务,下面为 A100-80G 测试时使用的参数,可以根据实际情况进行调整:
|
||
|
||
```shell
|
||
python -m fastdeploy.entrypoints.openai.api_server \
|
||
--model PaddlePaddle/PaddleOCR-VL \
|
||
--port 8118 \
|
||
--metrics-port 8471 \
|
||
--engine-worker-queue-port 8472 \
|
||
--cache-queue-port 55660 \
|
||
--max-model-len 16384 \
|
||
--max-num-batched-tokens 16384 \
|
||
--gpu-memory-utilization 0.7 \
|
||
--max-num-seqs 256 \
|
||
--workers 2 \
|
||
--graph-optimization-config '{"graph_opt_level":0, "use_cudagraph":true}'
|
||
```
|
||
|
||
2. 在同一环境安装依赖后启动测试脚本:
|
||
|
||
```shell
|
||
# 安装依赖
|
||
pip install -U paddlex
|
||
# 启动测试脚本
|
||
python benchmark.py ./test_data -b 512 -o ./benchmark.json --paddlex_config_path ./PaddleOCR-VL.yaml --gpu_ids 0
|
||
```
|
||
|
||
测试脚本参数说明:
|
||
|
||
<table>
|
||
<thead>
|
||
<tr>
|
||
<th>参数</th>
|
||
<th>说明</th>
|
||
</tr>
|
||
</thead>
|
||
<tbody>
|
||
<tr>
|
||
<td><code>input_dirs</code></td>
|
||
<td>输入的目录路径,会自动识别到目录下的 pdf 或图片。可以提供一个或多个。</td>
|
||
</tr>
|
||
<tr>
|
||
<td><code>-b, --batch_size</code></td>
|
||
<td>推理时使用的批处理大小。</td>
|
||
</tr>
|
||
<tr>
|
||
<td><code>-o, --output_path</code></td>
|
||
<td>输出结果文件的路径。</td>
|
||
</tr>
|
||
<tr>
|
||
<td><code>--paddlex_config_path</code></td>
|
||
<td>PaddleX 的 YAML 配置文件路径。</td>
|
||
</tr>
|
||
<tr>
|
||
<td><code>--gpu_ids</code></td>
|
||
<td>指定要使用的 GPU 设备 ID,可提供一个或多个。</td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
|
||
3. 测试结束后,会输出类似于下面的结果:
|
||
|
||
```text
|
||
Throughput (file): 1.3961 files per second
|
||
Average latency (batch): 351.0812 seconds
|
||
Processed pages: 981
|
||
Throughput (page): 1.3961 pages per second
|
||
Generated tokens: 1510337
|
||
Throughput (token): 2149.5 tokens per second
|
||
GPU utilization (%): 100.0, 0.0, 68.1
|
||
GPU memory usage (MB): 77664.8, 58802.8, 74402.7
|
||
```
|
||
|
||
输出结果说明:
|
||
|
||

|
||
<tr>
|
||
<th>参数</th>
|
||
<th>说明</th>
|
||

|
||
<tr>
|
||
<td>Throughput (file)</td>
|
||
<td>每秒处理的文件数量</td>
|
||
</tr>
|
||
<tr>
|
||
<td>Average latency (batch)</td>
|
||
<td>每批次处理的平均延迟时间,单位为秒</td>
|
||
</tr>
|
||
