[Xen-users] Slow windows network with gplpv driver.

[John McMonagle <johnm@xxxxxxxxxxx>]

This concerns an old problem
http://lists.xensource.com/archives/html/xen-users/2010-08/msg00567.html

Still having the problem with network performance but need to really fix it.

Just did a test with 32 bit xp with 0.11.0.238 drive.
it show device as Xen Net device driver.

Iperf gives 14.7 Mbits/sec

Running an xp live boot cd  get 13.6 Mbits/sec
Doesn't looks like the the pv driver is doing anything to help the network as 
there is probably extra load with no pv drivers for disk and display.

How much of a speed improvement are others seeing?

The real issue is speed for samba shares. 

I have tried on other hardware and it's a bit faster but not that impressive.
To keep the speed in perspective this is /proc/cpuinfo

8 cores like this:
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 15
model name      : Intel(R) Xeon(R) CPU           E5310  @ 1.60GHz
stepping        : 7
cpu MHz         : 1596.078
cache size      : 4096 KB
fpu             : yes
fpu_exception   : yes
cpuid level     : 10
wp              : yes

acpi mmx fxsr sse sse2 ss ht syscall nx lm constant_tsc rep_good aper
fmperf pni ssse3 cx16 hypervisor lahf_lm
bogomips        : 3192.15
clflush size    : 64
cache_alignment : 64
address sizes   : 36 bits physical, 48 bits virtual
power management:

Any suggestions?
I'm willing to try most anything as if I do not get this better I'll have a 
lot of work to do, redoing most everything :-(
