Applescript delay issue - applescript

Question

I am testing applescripts that I will use later in my OSX app.
I'm getting a 6 sec delay after the click button command below.
After some research it seems that this is a known issue.
What I find interesting is, if i use the commercial app QuicKeys to perform the same
button click there is no delay, so I assume they found a work around.
Anybody have any ideas?
tell application "System Events"
tell process "Pro Tools"
set frontmost to 1
click button "Track List pop-up" of window 1
-- 6 seconds delay before next command is sent
key code 36 -- return key stroke
end tell
end tell

Answer 1

Was having the same problem and resolved it by enclosing the click causing delay in the ignoring application responses block. Here is a quick summary:
OLD CODE (Causes 6 sec delay)
tell application "System Events" to tell process "SystemUIServer"
set bt to (first menu bar item whose description is "bluetooth") of menu bar 1
click bt
tell (first menu item whose title is "SBH80") of menu of bt
click
tell menu 1
if exists menu item "Disconnect" then
click menu item "Disconnect"
else
click menu item "Connect"
end if
end tell
end tell
end tell
NEW CODE (No delay)
tell application "System Events" to tell process "SystemUIServer"
set bt to (first menu bar item whose description is "bluetooth") of menu bar 1
ignoring application responses
click bt
end ignoring
end tell
do shell script "killall System\\ Events"
delay 0.1
tell application "System Events" to tell process "SystemUIServer"
tell (first menu item whose title is "SBH80") of menu of bt
click
tell menu 1
if exists menu item "Disconnect" then
click menu item "Disconnect"
else
click menu item "Connect"
end if
end tell
end tell
end tell

It seems click or axpress causes a big delay.
Instead - get position and use a third party shell script to do the clicking. Much Much faster.
using clicclik : https://www.bluem.net/en/mac/cliclick/
put in user library/application support/Click
set clickCommandPath to ((path to application support from user domain) as string) & "Click:cliclick"
set clickCommandPosix to POSIX path of clickCommandPath
tell application "System Events"
tell process "Pro Tools"
set frontmost to 1
tell button "Track List pop-up" of window 1
set {xPosition, yPosition} to position
set x to xPosition
set y to yPosition
end tell
do shell script quoted form of clickCommandPosix & " c:" & xPosition & "," & yPosition
key code 36 -- return key stroke
end tell
end tell
