这个问题属于技术问题,我可以回答。total_worker_time/qs.execution_count是用来计算平均每次查询执行的工作时间的公式。其中total_worker_time是指查询执行期间所有工作线程的总工作时间,qs.execution_count是指查询执行的次数。通过这个公式可以评估查询的性能。

These dependencies were not found: * canvas in ./node_modules/pdfh5/js/pdf.js * dommatrix/dist/dommatrix.js in ./node_modules/pdfh5/js/pdf.js, ./node_modules/pdfh5/js/pdf.worker.js * web-streams-polyfill/dist/ponyfill.js in ./node_modules/pdfh5/js/pdf.js, ./node_modules/pdfh5/js/pdf.worker.js
It seems that some dependencies required by PDFH5 are missing. To resolve these dependencies, you can follow these steps:
1. Install missing dependencies: Run the following command in your project's root folder to install the missing dependencies:
```shell
npm install canvas dommatrix web-streams-polyfill
```
This will install the required packages (`canvas`, `dommatrix`, and `web-streams-polyfill`) and add them to your project's `node_modules` folder.
2. Import the dependencies: In the file `pdf.js` located in `node_modules/pdfh5/js/`, add the following import statements at the top of the file:
```javascript
import 'canvas';
import 'dommatrix/dist/dommatrix.js';
import 'web-streams-polyfill/dist/ponyfill.js';
```
Similarly, in the file `pdf.worker.js` located in `node_modules/pdfh5/js/`, add the same import statements at the top of the file.
3. Save the changes and rebuild: After adding the import statements, save the files and rebuild your project. Depending on your build system (Webpack, Rollup, etc.), you might need to run a command like `npm run build` or `npm run dev` to rebuild your project with the updated dependencies.
By following these steps, you should be able to resolve the missing dependencies for PDFH5.
