Warning W5204 - CPU utilisation is high. Modern ATA and SCSI disk controllers use DMA bus-mastering which frees the CPU from transferring data from/to the disk and increase system peformance. Such systems typically use maximum 10% of CPU time while other systems use 90-99% of CPU time during transfers.
Fix: Check if the disk controller and drives support bus-mastering. If yes, check for updated drivers for the disk controller from the manufacturer. Refer to the manual for information on how to turn DMA bus-mastering on. If youΓÇÖre using the Windows bus-mastering drivers, check the DMA box in Control Panel\System\Device Manager\Disk Drives\Disk click Properties and open the Settings tab.
