In DB2, SMF Detail storage is allocated in Subpool 230 Key 0.
The recommendation is to have NODETAIL. You will see a huge difference
after you change it.
I recommend you to take a look at APAR II07124,

Does this help?

NODETAIL
DETAIL
Specifies the level of SMF data collection for TSO and STC; specifying
DETAIL or NODETAIL has no effect on any other types of work.
For TSO, when DETAIL is specified, type 32 SMF records contain the total
count of each TSO/E command used, CPU time under TCBs and SRBs, and the
total number of TGETs, TPUTs, EXCPs and transactions. When NODETAIL is
specified for TSO, type 32 SMF records contain only the total count of
each TSO/E command used.
For STC, specifying DETAIL has no effect. Specifying NODETAIL has an
effect only if INTERVAL is also specified. Specify NODETAIL and INTERVAL
to exclude the EXCP sections from SMF type 30 subtype 4 and subtype 5
records collected for started tasks. Otherwise, the EXCP sections for
SMF type 30 subtype 4 and subtype 5 records will be included.
Default: NODETAIL
