ADSM MVS Server 2.1.13

Can anyone running an MVS server provide me with information on the
dispatch priority you assign to ADSM?  We are experiencing some frustrating
problems in getting admin tasks performed due to lack of cpu, and were
wondering what others might be doing in this area.  We had difficulty
completing migration, reclamation and copy pool tasks all week last week
(monthend).  Thanks for any info you can provide,

                         Ginny
