Hi guys.
I have one table that currently has 100 000 000 records. PageSize is
16384.
Index statistics for primary key are 0.000000 (I've recomputed them).
Over a few days inserting and updating this table slowed down
significantly. When I try to update one row:
UPDATE TABLE SET VALUE=X WHERE PK_COLUMN_ID =12335343
update executes in 0.250 miliseconds.
What is surprising for me that just few days ago everything was fine..
how could I speed thing up? What could happen over these few days?
Thanks in advance.
It's hard to tell without more information.
But the first thing I would look out is the transaction counters.
Perhaps you have some open transaction that is preventing the garbage
collection process and acumulating record versions.
use GSTAT -h to get the header information of your database and post it
back.
see you !
