Overleaf超时
Opened this issue · 12 comments
发生了什么？
旧版本（yang yating等维护）在免费版本的Overleaf上可以正常完成编译。
而新版本（2024年推出，由Feng Kaiyu等维护）在Overleaf上内容较多（10万字，150+参考文献）时会造成超时，需要开通Overleaf会员才能完成编译，给学生带来了巨大困难。
你期望的结果
希望新版本可以适当改进以实现在内容较多时也可以在免费版本的Overleaf上完成编译
BIThesis 模板
graduate-thesis
之前有同学反映 www.overleaf.com 换成 cn.overleaf.com 就行，有没有试过呢？

感谢帮助，尝试了一下，还是出现了超时的情况。目前，我已经采用了Ruifeng Ma等同学在Overleaf上发布的新模板Beijing Institute of Technology (BIT) 2024 version thesis template（源于yang yating等维护的旧版本），该版本可以正常编译。
刚刚做了个十一万字的测试用例，还没有暴露问题。我之后加\cite试一下。
另：Beijing Institute of Technology (BIT) 2024 version thesis template - Overleaf 与 https://github.com/RuifMaxx/LaTeX-template 并不完全相同，Overleaf上的BIT-thesis-grd.cls似乎有更多刻意改动。
更新：加了十几个参考文献就会出现超时，但“从头开始重新编译”就不超了。
texpage https://www.texpage.com/pricing 提供了每次一分钟的免费编译时长。
减小包的依赖可能是唯一一个优化性能的手段。

刚刚我在 #536 补充了一下各家情况。
WARNING: Overleaf reduced the compile time
There is no way you can compile your thesis/dissertation (using this template) within the new (20 seconds) time limit. This means you have two options:
- Install LaTeX in your computer and use the template locally!
- Opt for a hassle-free solution and buy a (student) plan in Overleaf.

app.run()完整测试
- 实线使用 biblatex，点划线使用 natbib。
- empty 为空文档，packages 指 biblatex/natbib 等宏包，hooks 指
\frontmatter等钩子，full 表示完整十一万字的文档。
一些特殊情况：
\MakeCover等命令 ctex 没有，测试时统一删去了，包括 full 版本。BIT-thesis-grd.cls本身就引入了 natbib；而 bithesis 的*.cls并不引入，在*.tex中才引入。- 测试的是单次 xelatex 编译，而完整编译可能需要三次。
现象：
- 增多字数时，各模板增加的时间都差不多。
\usepackage[backend=biber]{biblatex}远比\usepackage{natbib}耗时。

像这种\clist_item其实每编译一页都运行了一遍，如果改改，应该可以总共只运行一遍。（肯定是从 O(n) 变成 O(1)，但实际效果我就不清楚了。）
