Dor,
I ran some netperf tests with your PV
virtio drivers, along with some Xen PV cases
and a few others for comparison. I thought you
(and the list) might be interested in the numbers.
I am going to start looking for bottlenecks, unless
you need help with the new hypercall updates.
I'll re-run when that is available.
Jim
Tests were run with Netperf-2.4.3, TCP Socket
buffers were 256k. All of the tests were run with
netserver in the guest, netperf in the host/dom0.
No bridge was used.
Hardware: IBM HS21 blade
Dual Xeon w/HT @ 1.6GHz, 4GB
The host/Dom0 configuration:
kvm.*:
Host is 32 bit Ubuntu 7.04 server running
Dor's 2.6.22-rc3 kernel.
xen.*:
Dom0 is 32 bit Ubuntu 7.04 server running
the 2.6.18 kernel from xen3.1
The guest configurations:
All guests/domUs are 512MB, 1 CPU
kvm.rtl: (KVM with emulated RTL8029)
Fedora 7 32 bit guest
Standard 2.6.21-1.3194.fc7 kernel
kvm.pv: (KVM w/Dor's paravirt drivers)
Fedora 7 32 bit guest running
Dor's 2.6.22-rc3 kernel.
xen.pv: (Xen paravirt)
Ubuntu 7.04 server w/2.6.18-xen kernel
xen.um: (Xen HVM with unmodified drivers)
Ubuntu 7.04 server w/2.6.18-xen kernel,
unmodified drivers compiled from xen3.1
kvm.lo: (Host loopback)
TCP REQUEST/RESPONSE (Trans. Rate per sec)
