Hi, Since we upgraded from MySql 3.20 to 4.1 innodb seems to have become slower.
I'd like to understand the innodb status a bit better. Here is a the slow innodb transaction ---TRANSACTION 0 2599083795, ACTIVE 72659 sec, process no 12324, OS thread id 1138606116 estimating records in index range mysql tables in use 1, locked 1 1527743 lock struct(s), heap size 127790400, undo log entries 127362260 MySQL thread id 8885936, query id 78269607 10.168.80.166 web init delete from negotiated_classes_cache where id=110495925522553001 Trx read view will not see trx with id >= 0 2599083796, sees < 0 2599083791 What exactly does this mean ? And why would this query take so long ? In this table Id is the primary key. The machine that this is running on is a Dell quad Xeon and the data is stored on a SAN. The machine is not showing high load at all. I'd be grateful for your advice. Please let me know if I should provide any more information.
