Download speed from VM is fine:

[otherhost.othernet] wget vm.mynet/testspeed.o
--2010-10-30 15:25:57-- vm.mynet/testspeed.o
Connecting to ##.##.##.##:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 369834552 (353M) [application/x-object]
Saving to: `testspeed.o.2'

83% [========================================> ] 310,615,928 87.7M/s eta 1s

But download speed from VM itself is terrible:

[vm.mynet] wget otherhost.othernet/testspeed.o
--15:24:14-- otherhost.othernet/testspeed.o
=> `testspeed.o.7'
Resolving otherhost.othernet... ##.##.##.##
Connecting to otherhost.othernet|##.##.##.##|:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 369,834,552 (353M) [text/plain]

0% [ ] 580,372 13.15K/s ETA 8:44:57

Why?

The same VM, seme venet... all the same.
No modifications have been made in sysctl.

Possible reason? Howto explore?...

Problem was already sold. Close the topic.

"""It describes a similar effect, with a comment (#2) describing a workaround:
i.e: ethtool -K eth0 rx off"""

In my case, also: ethtool -K eth0 tx off
