I looked through the code to see how the time is measured. There are two functions timer_start and timer_stop for this.
The first, timer_start, is called in wp-config.php. This is in turn included by admin.php which seems to be used in for example moderation.php -- and this is a top level module called from the users web browser.
At the end moderation.php includes admin-footer.php and in admin-footer.php timer_stop is called.
So the time measured is all about time on the web server.
The reason am interested in this is that my web hostel asks me to check for network delays. I can not see at all that network delays are involved here.
Any suggestion of what to do. Should I publish the name of the web hostel, or?
