Native linux writes at 6MB/s without any hdparm tuning. The SCSI hosts seem fine. native linux writes to scsi at 36MB/s and xen at 28MB/s. Is the IDE speed about what I should expect for xen-1.2 or did I screw up my configuration? ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
