slow in emacs

[freddez]

Hello,

I don't know why, but ripgrep is really slow on emacs :

• if I do a simple search (find an expr in ~20 source files), it tooks 3 seconds
• if I paste rg expression in terminal, I have an immediate output
• if I do a rgrep in emacs, no problem.

GNU Emacs 25.2.50.2 (x86_64-pc-linux-gnu, GTK+ Version 3.22.11) of 2017-07-03
ripgrep 0.5.2

Do you have an idea ?

Strange. which version of Emacs and ripgrep do you use ?
I've got same behavior in Emacs and shell.

I've done some profiling:

- redisplay_internal (C function)                                2929  96%
 - jit-lock-function                                             2929  96%
  - jit-lock-fontify-now                                         2929  96%
   - jit-lock--run-functions                                     2929  96%
    - run-hook-wrapped                                           2929  96%

      - font-lock-fontify-region                                 2929  96%
       - font-lock-default-fontify-region                        2929  96%
          font-lock-fontify-keywords-region                      2929  96%
+ command-execute                                                  86   2%
+ ...                                                              16   0%

With rgrep function, the redisplay internal is lowered to 2% of the cpu
