after upgrading to V3.6.6 merged tickets are really slow.
After doing a bit research, I saw a lot of MySQL entrys stating that
get_lock queries took a long time:
Query_time: 69 Lock_time: 0 Rows_sent: 1 Rows_examined: 0
I first converted the table to innodb and then changed the session
backend to Apache::Session::File. Now the mysql log entries are gone
but the ticket system is not faster than before…
However, this does only affect merged tickets.
It seems that rt locks and tries to access the locked data in some way
because it used to be two tickets?
Has anyone else experienced this behaviour and dound a solution?
