hexo generate 耗时太长

[wgzhao]

使用当前最新版的hexo，Mac平台下，300+文章量，执行 hexo g --debug 耗时长达356.396s!! 比octopress的耗时还要长。

在1000+文章量的情况下，耗时长达不可思议的38分钟。 完全无法接受了。

附件是debug文件（修改了后缀）

I can't see the picture. Please post the debug message directly.

下面是当时的日志，重复的部分删除了，否则太长了

从日志来看，是等待了很长一段时间才开始写发布文件，怀疑是我的硬盘问题，切换到一台安装有SSD硬盘的机器上跑hexo generate，依然如此。

[tommy351]

如果可以的話，可以把整個網站打包寄給我，我試著跑profiling看是那個環節花特別多時間。

谢谢！

[tommy351]

剛剛測試了一下，耗時的確非常異常，profiler中顯示/usr/lib/system/libsystem_kernel.dylib佔用了54.2%的CPU時間，可能是某些東西堵塞了。

[wgzhao]

会不会是某个帖子的某个语法或者格式触发了一个异常？

[tommy351]

Profiling result: https://gist.github.com/tommy351/9595962

[wgzhao]

写了个脚本，逐一把帖子按照时间先后顺序加入到_posts目录，然后生成，大致时间如下：

帖子数	耗时(s)
104	60
112	70
126	90
134	100
142	120
