I think it will require quite large script for the slow-down to happen but it could happen, for example printing large matrices (generally by accident as JMP always "prints" the last line) will have an impact on the script editor due to the log print. And also clearing such prints usually has to be done with Clear Log() as if you try the "quick" option of Ctrl + A and Delete it can be very slow.
This will slow down script editor most likely due to the log print (over 120 000 characters) as this does close fairly fast if nothing is being printed to script editors log (Enhanced log will limit the size it shows by cutting it at some point (seems to be about 10 000 characters) and adding ...)
