=head1 DESCRIPTION |
23
|
|
|
|
|
|
|
|
24
|
|
|
|
|
|
|
Remembers timing at the given points during template processing and |
25
|
|
|
|
|
|
|
reports on them later. The tag is required for 'enter' and 'leave' |
26
|
|
|
|
|
|
|
modes. |
27
|
|
|
|
|
|
|
|
28
|
|
|
|
|
|
|
System-wide benchmarking can also be controlled with 'system-start' |
29
|
|
|
|
|
|
|
and 'system-stop' modes. With that all sub-templates are individually |
30
|
|
|
|
|
|
|
benchmarked. The tags are automatically build based on their 'path' or |
31
|
|
|
|
|
|
|
'template' arguments. |
32
|
|
|
|
|
|
|
|
33
|
|
|
|
|
|
|
Results can be retrieved using 'stats' mode. With a 'dprint' parameter |
34
|
|
|
|
|
|
|
it will dump results using the dprint() call to be seen in the server |
35
|
|
|
|
|
|
|
log typically. Given a template or a path the results can be included in |
36
|
|
|
|
|
|
|
the rendered page. |
