DB2 FOR LUW / DB2FORLUW / A50 - DB2

It is possible to observe a drop in performance when there are 
many concurrently running tasks requiring new extents to be 
allocated in a single tablespace. 
DB2 searches the Space Map Pages to find free extents. 
When there are no free extents tracked in these SMP pages, it is 
possible that DB2 performs repeated searches on SMP pages known 
to contain no free extent references. 
This can lead to a contention for the different tasks requiring 
a new extent, when there is a long chain of such SMP pages. 
( e.g. in a large tablespace with a small extent size.  )

Create a tablespace with a larger extent size thereby reducing 
the number of SMP pages required. 
Split tables into several table spaces.
