各位，我使用的 purcell-emacs.d 配置
emacs 25.3.1 Fedora 28
C-x C-f (counsel-find-file) 打开 .ts 文件时 minibuffer 会 hang 住，需要 C-g 关闭 minibuffer 重新使用 C-x C-f (counsel-find-file) 再次定位 .ts 文件才能正常打开。
使用 C-x C-f (counsel-find-file) 打开 .md 、.html 等文件时不会 hang 住。
不知道如何调试并定位问题：是 C-x C-f (counsel-find-file) 原因还是其他问题
感谢～
用内置命令打开一次试试
诊断：
M-x profiler-start 选 cpuC-x C-f (counsel-find-file)，hang 一段时间，然后 C-g
M-x profiler-report 看哪一步消耗资源最多M-x profiler-report 输出如下：
