Setting parameters for Managing Concurrent Manager & processes

Hi,

We face regular performance issue, i referred a metalink note Concurrent Processing - Best Practices for Performance for Concurrent Managers in E-Business Suite (Doc ID 1057802.1), but need clarifications on how to evaluate my current settings and setup parameters in relation to my Concurrent Manager & processes to best fit & manager the job loads & queue.

Our standard manager, we have defined Cache Size as 5, Processes 60, Sleep Seconds 10.

We also have defined custom managers for each module - GL, AR, AP, INV, WIP, BOM number of processes differ from 10 to 40 and cache size is same.

Please someone guide on which parameters should be evaludated & what could be best setting for managing the processes.
