I wasted a good part of the last few days being plagued by a really bad slowdown  in many places.  The particular test case that I used was saying "Press Delete"  repeatedly in Thunderbird.  This should take less than a second,  but it was taking 5-6 seconds.

 

I have documented my experience in 

https://github.com/AndyGlew/manx-UI--Speech/wiki/Performance-Issues-with-Dragon-Speech-Recognition#56_second_stalls_saying_press_delete

 

Briefly: two components:

 

1.  "Enable launching from the desktop" was on

 

2.  the desktop contained files with "Nms_Dgn_cld_nt_pronce.txt"

 

It seems that Dragon  decided that such files  match almost any utterance, slowing everything down.   Or something similar.

 

Disabling "Enable launching from the desktop"  worked around the problem. 

 

As did making the filenames more pronounceable, although obviously the latter is  fragile,  and will break again the next time you have unfortunate files.

Posting just in the hope of saving somebody some time someday.  Possibly myself,  since I am fairly certain I have encountered this problem before, and had just forgotten about it, and had not automated mitigation.
