I have the disk performance test program Bonnie running on RTEMS.
I could place a copy on the RTEMS ftp incoming directory if you are interested in

On the subject of performance, I noticed in the ATA driver:

areq = malloc(sizeof(ata_req_t));
if (areq == NULL)
Does this mean each ATA request is performing a malloc ?
