Not sure if DCCP might fall into this category as well...
I think the idea of this patch is gather some number of these small packets and
shove them at the driver in one go instead of each small packet at a time.
This reminds me... (rick starts waxing rhapshodic about old HP-UX behviour :)

The win might be biggest on a system were a lot of applications send a lot of

That's assuming that the device doesn't run out of things
Bill,
Could you test with the lastest version of CUBIC? this is not the latest
version of it you tested.

As a followup, I ran a somewhat interesting test. I increased the
requested socket buffer size to 100 MB, which is sufficient to
overstress the capabilities of the netem delay
small packets belonging to the same connection could be coalesced by
TCP, but this may help the case where multiple parallel connections are
sending small packets.
It's not just small packets. The cost of calling hard_start_xmit/byte
was rather high on your particular device. I've seen PCI

Again, you're comparing these patches
Hi all,
Here comes a basic patch that adds a network led activity. It is not
configurable yet, but is enough to make a LED configured with
the network-activity trigger to blink on network activity.
Netdev people can probably comment on the place of ledtrig_network_activity(),
which is
The discussion seems to have steered into protocol coalescing.
My tests for example were related to forwarding and not specific
to any protocol.

Just the natural tendency of end-system types to think of end-system things
rather than router things.

You would need to almost re-write the driver to make sure it does IO
which is taking advantage of the batching.
Really! It's just the transmit routine. How radical can that be?

Well router types felt they were being left out ;-
