Cross-process messaging time can be reduced quite a bit by delegating communications to 'run script':

script
   tell application "Blah"
     -- Do several interesting things.
   end tell
end script

run script result

‘run script’ best practices:

1. Don't send ‘run script’ to another process unless the performance overhead is a serious impediment. Scripts aren't guaranteed to run correctly when sent to another process.

2. If you're using ‘run script’ with source text, explicitly indicate the script language with the ‘in’ parameter, otherwise the language used to compile will depend on the current default language inside the target process, which could change at any moment. Better yet, compile the script, save it in a file and use ‘run script’ to run the compiled script file instead.

run script v : Run a specified script or script file

run script script : the script text (or an alias or file reference to a script file) to run

[with parameters list of any] : a list of parameters

[in text] : the scripting component to use; default is the current scripting component

→ any : the result of running the script
