伺服 Web 引擎性能进一步优化
Servo Web Engine Further Tuning Performance

Servo,一个开源的网页布局引擎,正在稳步发展,最近的开发重点在于功能和嵌入能力。最新的月度更新强调了改进,包括增量布局处理和各种性能优化。 关键进展包括对viewport meta标签、滚动事件和基本IndexedDB功能等基本网页特性的支持。开发者也在通过WebDriver服务器支持来增强自动化,并使用`AbortController`实现来改进中止处理。 值得注意的是,实验性的多进程模式现在在Windows上可用,并且DevTools支持正在扩展。可访问性也是一个优先事项,Servoshell浏览器UI已经增加了初步的屏幕阅读器兼容性。这些更新展示了Servo朝着一个强大而通用的网页渲染引擎持续演进。更多细节请访问官方Servo.org博客。

最近对Servo网页引擎的更新主要集中在性能改进上,特别是通过“增量布局”优化。这一点很重要,因为样式、绘制和脚本已经利用与Firefox共享的技术(Stylo、WebRender、SpiderMonkey)得到了很好的优化。 然而,有用户报告称在Windows 11上使用特定字体和调整窗口大小会导致文本渲染问题,出现闪烁和布局不一致的情况。这表明还需要进一步的工作来适应更广泛的平台。 讨论的中心是Servo的潜力。虽然实现完全的浏览器竞争力仍然是一个问题,但有些人认为Servo在作为其他应用程序的渲染引擎方面具有强大的利基市场——例如,作为Electron的更快替代方案或用于网页抓取——这可能提供一条可行的前进道路。像Ladybird Browser的月度报告这样的资源提供了持续的性能比较。

The Servo open-source web layout engine continues advancing with its demo Servoshell and continued work around making it suitable for embedding into other software. The Servo project this morning published their latest monthly status update to inform the community what they have been up to the past several weeks.

For those curious what Servo developers have been backing on this summer, some of the highlights they published today on their development blog include:

- Servo landed some additional work towards supporting incremental layout handling.

- Various other performance optimizations.

- Continued work on WebDriver server support to be able to automate Servo.

- Support for viewport meta tags.

- Support for scroll events in the DOM.

- Barebones IndexedDB support.

- Support for abort() and signal on AbortController and other abort handling improvements.

- Experimental multi-process mode is now working on Microsoft Windows.

- Support for DevTools is becoming more capable with more functionality now implemented.

- Support for using a screen reader with Servo's basic servoshell browser UI.
