[drupal-devel] [feature] Add timing information to statistics page

[Amazon]

Issue status update for http://drupal.org/node/22623

 Project:      Drupal
 Version:      cvs
 Component:    statistics.module
 Category:     feature requests
 Priority:     normal
 Assigned to:  Anonymous

 Status:       patch

It's great to have this level of logging granularity.


I am concerned that all the logging would add over head when having
multiple crawlers crawling the site during testing.  Would it be
possible to support batching the log entries and submitting them to the
database as batch query at set increments instead of for every page.


For example I routinely run several wget crawls for different roles
when testing an upgrade.  If I ran 5 crawlers and each of 10, 000+
pages were being crawled then I am concerned the performance would be
impacted.


I understand this isn't the intent of this patch but non intrusive
logging is important in generating accurate performance measurements.


Thank-you for your consideration.

I extended the current timer_start() function in bootstrap.inc and added
two new function, timer_read() and timer_stop().  I've used these to
profile drupal.org.  (A small change will be needed to devel.module.)


I've also extended the accesslog-table to keep track of page generation
times.  The information is shown on the "top pages" page
(admin/logs/pages).  It shows each page's average page generation time,
and the total page generation time.  This lets one identify (i) slow
pages and (ii) resource heavy pages.  This is the most essential and
most useful information when tuning your Drupal site.


Please review, or I'll commit it as is.

looks ok ... note that there are some unrelated (i think) variable_set()
changes in the patch.
