### Describe your question, feature request, or bug.

Very slow to start and takes around 3 secs until appears. 

I did some profiling both in python and in neovim (see attached)

I did the profiling on slightly different version (on key mapping only)  , but checked it on the last one (from today).

### Steps to reproduce

IDK, I tried with leaderf as only plugin and it did OK (didn't happen)_

I tried just disabling all au and it was slow. 
I tried disabling popup and it was slow. 
Tried closing all other buffers.

nmap , Leaderf line

This is my mapping^

For debug 

nmap , call Lff() function! Lff() py3 << EOF import cProfile import pstats profiler = cProfile.Profile() profiler.enable() anyHub.start('line') profiler.disable() stats = pstats.Stats(profiler).sort_stats('cumulative') stats.dump_stats('output.pstats') EOF endfunction

### Actual behaviour

### Expected behaviour

[eyalk11]

output.pstats.txt

That is python pstat file. IIRC the wait time is mainly when waiting for vim. RPC

[eyalk11]

Apparently, it is reasonable after I removed some mappings. The nowait had limited effected for some reason. Still takes around 1.5 sec

[Yggdroot]

What about using :Leaderf line directly?

[eyalk11]

It should be probably 1.5 sec as well. Now it seems fine. I just have to open bug sometimes for something to be solved.
