I've attemped to speed up page load in all problematic cases by leaving Maximum Row Count blank. Usually it helps, but on specific page I noticed under debug, that if I remove Maximum Row Count 1000000, then another part becomes a problem taking either as much time or more, and that's last IR binding value, so:
| 0.24161 | 107.79628 | IR binding: "F_USER_NAME" value="" |
So 107.79628 is elapsed time, which is way over the top.
And I simply don't understand where to look up anything related to this. What am I even looking at here exactly? IR bind variable assigned empty value?
