Ich habe mal einen kleinen Profiler gebastelt - als Patch, da das mit einem Plugin nicht so ohne weiteres geht. Die angehängte Datei kann mit meinem Patches-Plugin angewendet werden, ansonsten ist von Hand zu editieren.

Das erzeugt dann eine Ausgabe der Form Zeit => Hook oder Query.

Code:

...

    [0.1339800] => hook_by_ref my_date

    [0.1556530] => before query
                    REPLACE INTO mybb_threadsread (tid, uid, dateline)
                    VALUES('295381', '100001', '1298300027')
                
    [0.1558521] => after query
                    REPLACE INTO mybb_threadsread (tid, uid, dateline)
                    VALUES('295381', '100001', '1298300027')
                
    [0.1558800] => before query
                    SELECT COUNT(t.tid) AS unread_count
                    FROM mybb_threads t
                    LEFT JOIN mybb_threadsread tr ON (tr.tid=t.tid AND tr.uid='100001')

    [0.1833060] => after query
                    SELECT COUNT(t.tid) AS unread_count
                    FROM mybb_threads t
                    LEFT JOIN mybb_threadsread tr ON (tr.tid=t.tid AND tr.uid='100001')
                    LEFT JOIN mybb_forumsread fr ON (fr.fid=t.fid AND fr.uid='100001')

    [0.1834669] => hook showthread_ismod
...

Daran läßt sich dann der Zeitverlauf eines Requests so einigermaßen nachvollziehen.

Sehr geil zum debuggen, danke!
