Hi

After upgrading our 9.0 database server

from:
openSUSE 11.4, kernel 2.6.37.6-24-default, Pg 9.0.13

to:
openSUSE 13.1, kernel v 3.11.10-21-default, Pg 9.0.15

... and  overall server load is +1 after that.

We did not add any new services/daemons.

It's hard to track down to individual queries - when I tested most
individual query times are same as before the migration.


Any - ANY - hints will be much appreciated.

Thanks
Filip
