Of course it depends, but 20000 for buffer pool 0 could be low as well. Any chance you can actually analyze the buffer pool performance statistics? Example information on the subject: https://www.ibm.com/support/knowledgecenter/en/SSFKSJ_8.0.0/com.ibm.mq.mon.doc/q038340_.htm.
Otherwise the following mentions real storage: https://www.ibm.com/support/knowledgecenter/SSFKSJ_8.0.0/com.ibm.mq.pla.doc/q006005_.htm.

Does someone know what effect upping MQ pools will have? Many Thanks in advance, Dave From: Hansen, Dave L - Eagan, MN Sent: Monday, July 18, 2016 3:26 PM To: '[email protected]' Subject: MQ Buffer expansion Dear Group, Our buffer pools may be too small. I see Pool 0 and Pool 1 as 2000 buffers instead of the 20000 suggested by IBM. The page sets show NO Expansion count. My CHIN goes into message allocation and drops the Channel with ETIMEDOUT. Q). If I up my Pools by ten-fold, will I have to worry where the storage comes out of? Like CSA is for CICS, or something?
