My Client has following situation:

one AS/400 model 720 as backend server to service 4 frontend AS/400 270 with 
Data queue to transfer data from frontend to backend.
The backend had 80~90% disk busy, but the CPU Utilization usage only 20~30% on 
peak time for data receiving from forntend.
The situation drivened the system tempary hanged for interactive job. When 
lower data transfer load, the system CPU utilization usage always 100% and Disk 
busy also 80~90% for interactive job. So the lower data transfer load is 
normal. Why heavy data transfer load from frontend drivened the Disk IO Bound 
and downing the system throughput ? Which system job handle the receiving data 
queue data from another AS/400 ? How do I solve this condition ?

Best Regards,
