Subject: How virtio-blk latency can be measured
Date: Sun, 15 Dec 2013 16:06:27 +0800 [thread overview]
Message-ID: <1387094787.18543.9.camel@debian.debian.ipads.com> (raw)
hi,I want to calculate the latencyof virtio in kvm, I read the document
in http://www.linux-kvm.org/page/Virtio/Block/Latency and met some
problem.
1. when calculating latency in kvm, the document said kvm_pio and
kvm_set_irq can be filtered using command 'lspci -vv -nn' and
'cat /proc/interrupts' , but I don't know how to use the result to
filter kvm_pio and kvm_set_irq.
2. Anyone know who is the author of this webpage:
http://www.linux-kvm.org/page/Virtio/Block/Latency .
Thank you.
