l
Hover the mouse over a value in the column Elapsed to see the time elapsed (in
milliseconds) since the start of the session. In the Scripts Profiler, the scripts are by
default sorted based on the values in the Elapsed column, from high to low.
l
Hover the mouse over a value the column Delta to see the difference between the time
elapsed (in milliseconds) in the previous session and in the current session.
The script execution stages are:
Query: the time it takes to find the selector in the template.
Tip
Looking for text is a rather lengthy operation. Use an ID (possibly in combination with a
text) instead of a text selector to make the query faster. For more tips, see "Optimizing
scripts" on the next page.
Execution: the time it takes to execute the script. If you are an experienced JavaScript coder
you may be able to optimize the code to speed up the execution of the script.
Tip
Functions that actually change the content of the template (for example,append()) are
comparatively time consuming. Avoid using such functions in a loop. For more tips, see
"Optimizing scripts" on the next page.
Note that the times vary slightly per run of the Script Profiler. Run the Script Profiler a number of
times and calculate an average from the results, before trying to speed up the execution of a
script.
Script Profiler settings
Number of runs
By default, the Script Profiler runs on 1000 instances of all the scripts. To test on a higher or
lower number of instances:
