In-Reply-To: <1247872416-17834-1-git-send-email-andy.grover@oracle.com>
Add a comment for what's going on. Remove negative logic.
I find this much easier to understand quickly, although
there are a few lines duplicated.

Yes, I am quite impressed that the Linux kernel and TCP/IP network
stack performs amazingly well at these multi-10-GigE speeds. I was
especially interested in Jesper's IP forwarding results, as we haven't
tested that yet ourselves, and one of the intended applications of
these systems is as a multi-10-GigE firewall, so that's looking very
encouraging at this point.

Note:
The mount point selection could be improved. I first had a trailing slash
after the mount point and that resulted in all mounts being included in the
output. Removing the slash helped.

Completion or congestion notifications were not being checked
if the socket went to sleep. This patch fixes that.

Since RDS 3.0 and 3.1 have different packet formats,
we need to wait until after protocol negotiation
is complete to layout the rx buffers.

* [PATCH 07/15] RDS: Don't set c_version in __rds_conn_create()
From: Andy Grover @ 2009-07-17 23:13 UTC (permalink / raw)
To: netdev; +Cc: rds-devel
In-Reply-To: <1247872416-17834-1-git-send-email-andy.grover@oracle.com>
Protocol negotiation is logically a property of the
transports, so rds core need not set it.

* [PATCH 06/15] RDS/IB: Rename byte_len to data_len to enhance readability
From: Andy Grover @ 2009-07-17 23:13 UTC (permalink / raw)
To: netdev; +Cc: rds-devel
In-Reply-To: <1247872416-17834-1-git-send-email-andy.grover@oracle.com>
Of course len is in bytes. Calling it data_len hopefully indicates
a little better what the variable is actually for.

Have you tried running nfs-iostat from the nfs-utils package to try and
figure out what the latency is on each READ request from the client?
http://git.linux-nfs.org/?p=steved/nfs-utils.git;a=blob_plain;f=tools/nfs-iostat/nfs-iostat.py;hb=HEAD
You need to run something like
nfs-iostat --page 20 10 /src/<mountpoint>
while running the vlc app.

While playing a video (avi) file from an nfs4 share using vlc I'm getting
significant latencies on the client resulting in video skips every 10-30
seconds. latencytop gives me for example:

There is no other NFS access going on at the time; just reading the single
file. No significant other processes running on either the client or the
server. latencytop on the server does not show any significant latencies.
Both server and client are dual core x86_64 running 2.6.30.1 with
identical configs (attached); Debian stable.
From /etc/exports on the server:
/srv/exports 10.19.66.0/24(rw,fsid=0,subtree_check,sync)
/srv/exports/myshare 10.19.66.0/24(rw,subtree_check,sync,mp,nohide)
mount on the client:
elrond:/myshare on /srv/<mountpoint> type nfs4 (rw,addr=10.19.66.2)
Cheers,

* [PATCH] TCP: Add comments to (near) all functions in tcp_output.c
From: Andi Kleen @ 2009-07-17 20:40 UTC (permalink / raw)
To: netdev, davem
TCP: Add comments to (near) all functions in tcp_output.c
While looking for something else I spent some time adding
one liner comments to the tcp_output.c functions that
didn't have any. That makes the comments more consistent.
I hope I documented everything right.
No code changes.

> 10-GigE interfaces is about 93%).
Hey guys, those are really nice numbers. Since TCP splicing appeared in the
kernel (once we got it fixed), I achieved 10 Gbps of HTTP proxying using
haproxy with very low CPU usage (about 20% of a Core2Duo 2.66 GHz).
Before buying the machines, I had been wandering around with the NICs
donated by Myricom in order to try to find a machine capable of supporting
this. My conclusion was that a lot of machines had difficulties getting
above 3.5, 4.7 and 6.5 Gbps of output traffic (those 3 numbers were always
the same, depending on the chipsets). There clearly was a bandwidth
limitation imposed by the chipset.
So I waited for the X38 and AM780FX chipsets to become available and
bought 3 machines (1 C2D, 1 AMD X2, 1 AMD X4). Those ones have no problem
with 10 Gbps of forwarded traffic (20 Gbps of total bus bandwidth), even
with 1500 bytes frames, but I don't know how high they can go, maybe
they will saturate slightly above.
Unfortunately, I only have 5 NICs in 3 machines and no switch (and CX4
is hard to find these days), so I'm probably stuck at 10 Gbps max.
Interestingly, I had the impression that forwarding data with TCP
splicing costs less CPU than IP forwarding, because the NICs can do
LRO.
Also, I know a french service provider who uses haproxy on Core i7
machines and who has already reached 5 Gbps of sustained traffic
with recent intel dual-port NICs (though I'm not sure exactly which
ones). This is with very little CPU usage too, less than 2-3% user
and 15% system+softirq. On previous machines (quad core xeons), it
was impossible to go beyond 3 Gbps, it looked like the chipset was
the limitating factor too (though I don't precisely remember which
one it was).
I really blamed the NICs because this guys machine was about 4 times
more powerful than mine, but apparently it was just a chipset issue.
I also happen to have a customer who recently received a few Sun NXGE,
mounted in Sun x2100-m2 using an nvidia chipset which I tested OK at
10 Gbps with my myri10GE NICs. I'll try to see if I can run some tests
there, as Davem once said those NICs are really good too.
All in all, I find it really cool that our beloved OS scales that
well with the hardware :-)

Willy

eth_type_trans does not need to even be called assuming that the
packet type information can be inferred from the RX descriptor. We
are doing steering completely based on contents of the RX descriptor.

The following patch is _in addition_ to the one I sent out yesterday.
Since they are independent, and fix different bugs, I'm leaving them
separate.
I guess it's clear not many people are running authenticated BGP
sessions on Linux...

[PATCH] tcp: Use correct peer adr when copying MD5 keys
When the TCP connection handshake completes on the passive
side, a variety of state must be set up in the "child" sock,
including the key if MD5 authentication is being used. Fix TCP
for both address families to label the key with the peer's
destination address, rather than the address from the listening
sock, which is usually the wildcard.

No, there's a deeper issues here. I'm bothered that the mac driver is
impacting the mdio driver. I'd like to find a way for this whole
thing to be handled cleaner, and not have two different drivers
calculate it.

Good point.
Depending upon the cache line size, however, we might have
at least the IP header in the cpu cache at this point since
eth_type_trans() had to pull in the entire ethernet header
underneath.
I totally misunderstood you, I thought you meant that with a
pure SW hash implementation, Toeplitz did better than jhash.

The advantage is that Toeplitz, or any reasonable device provided
hash, allows packet steering to be done without taking any cache
misses on the packet itself. In particular, this helps with a NIC
that just provides Toeplitz hash (without multiQ),

If you like, I can re-introduce the mpc5xxx_get_mii_speed() I unrolled
