* Jaye Mathisen | 8 parallel DD's started at the same type creating 2GB cycbuffs (as fast as | & can put them in the background). (dd if=/dev/zero bs=1m count=2000 | of=blahblah) | | Any brilliant ideas? I've also experienced this on my scsi-drives (dual P2-350, adaptec2940u2w controller). When doing extensive writes, this always happens. The scan-rate (reported by vmstat) goes sky high, and the system becomes unresponsive. -- Andreas Dobloug : email: andreasd@ifi.uio.no To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
