[rt-users] Slow MySQL after upgrade from 3.8.6 to 3.8.8

[Foggi, Nicola]

I had the same problem and ended up dropping the Groups2 index and performance went back to "normal"

Hi,

                Since upgrading from 3.8.6 to 3.8.8 our RT system has
been very slow to return any pages containing ticket data such as the
home page, searches and tickets themselves.

 

I enabled the MySQL slow running query log and this was at the top of
the list:

 

mysqldumpslow -t 10 /var/log/mysql/mysql-slow.log

Reading mysql slow query log from /var/log/mysql/mysql-slow.log

Count: 47  Time=10.12s (475s)  Lock=0.00s (0s)  Rows=1.0 (47),
rtuser[rtuser]@*************

  SELECT GET_LOCK('S', N)

 

Any ideas?

 

Thanks.
