By changing a few sysctl parameters. eth4: Device is on 64 bit 133MHz PCIX(M1) bus
Copy the following lines into a file and run the following command,

### IPV4 specific settings driver version, interface name(eth3, eth4), Interrupt type(INTA, MSI, MSI-X).
net.ipv4.tcp_timestamps = 0 # turns TCP timestamp support off, default 1, reduces CPU use In case of Xframe II, the PCI/PCI-X bus width and frequency are displayed
net.ipv4.tcp_sack = 0 # turn SACK support off, default on as well.
# on systems with a VERY fast bus -> memory interface this is the big gainer
net.ipv4.tcp_rmem = 10000000 10000000 10000000 # sets min/default/max TCP read buffer, default 4096 87380 174760 To associate an interface with a physical adapter use "ethtool -p <ethX>".
net.ipv4.tcp_wmem = 10000000 10000000 10000000 # sets min/pressure/max TCP write buffer, default 4096 16384 131072 The corresponding adapter's LED will blink multiple times.
net.ipv4.tcp_mem = 10000000 10000000 10000000 # sets min/pressure/max TCP buffer space, default 31744 32256 32768
3. Features supported:
### CORE settings (mostly for socket and UDP effect) a. Jumbo frames. Xframe I/II supports MTU upto 9600 bytes,
net.core.rmem_max = 524287 # maximum receive socket buffer size, default 131071 modifiable using ifconfig command.
net.core.wmem_max = 524287 # maximum send socket buffer size, default 131071
net.core.rmem_default = 524287 # default receive socket buffer size, default 65535 b. Offloads. Supports checksum offload(TCP/UDP/IP) on transmit
net.core.wmem_default = 524287 # default send socket buffer size, default 65535 and receive, TSO.
net.core.optmem_max = 524287 # maximum amount of option memory buffers, default 10240
net.core.netdev_max_backlog = 300000 # number of unprocessed input packets before kernel starts dropping them, default 300 c. Multi-buffer receive mode. Scattering of packet across multiple
---End of performance tuning file--- buffers. Currently driver supports 2-buffer mode which yields
significant performance improvement on certain platforms(SGI Altix,
IBM xSeries).
d. MSI/MSI-X. Can be enabled on platforms which support this feature
(IA64, Xeon) resulting in noticeable performance improvement(upto 7%
on certain platforms).
e. NAPI. Compile-time option(CONFIG_S2IO_NAPI) for better Rx interrupt
moderation.
f. Statistics. Comprehensive MAC-level and software statistics displayed
using "ethtool -S" option.
g. Multi-FIFO/Ring. Supports up to 8 transmit queues and receive rings,
with multiple steering options.
4. Command line parameters
a. tx_fifo_num
Number of transmit queues
Valid range: 1-8
Default: 1
b. rx_ring_num
Number of receive rings
Valid range: 1-8
Default: 1
c. tx_fifo_len
Size of each transmit queue
Valid range: Total length of all queues should not exceed 8192
Default: 4096
d. rx_ring_sz
Size of each receive ring(in 4K blocks)
Valid range: Limited by memory on system
Default: 30
e. intr_type
Specifies interrupt type. Possible values 1(INTA), 2(MSI), 3(MSI-X)
Valid range: 1-3
Default: 1
5. Performance suggestions
General:
a. Set MTU to maximum(9000 for switch setup, 9600 in back-to-back configuration)
b. Set TCP windows size to optimal value.
For instance, for MTU=1500 a value of 210K has been observed to result in
good performance.
# sysctl -w net.ipv4.tcp_rmem="210000 210000 210000"
# sysctl -w net.ipv4.tcp_wmem="210000 210000 210000"
For MTU=9000, TCP window size of 10 MB is recommended.
# sysctl -w net.ipv4.tcp_rmem="10000000 10000000 10000000"
# sysctl -w net.ipv4.tcp_wmem="10000000 10000000 10000000"
Transmit performance:
a. By default, the driver respects BIOS settings for PCI bus parameters.
However, you may want to experiment with PCI bus parameters
max-split-transactions(MOST) and MMRBC (use setpci command).
A MOST value of 2 has been found optimal for Opterons and 3 for Itanium.
It could be different for your hardware.
Set MMRBC to 4K**.
For example you can set
For opteron
#setpci -d 17d5:* 62=1d
For Itanium
#setpci -d 17d5:* 62=3d
For detailed description of the PCI registers, please see Xframe User Guide.
b. Ensure Transmit Checksum offload is enabled. Use ethtool to set/verify this
parameter.
c. Turn on TSO(using "ethtool -K")
# ethtool -K <ethX> tso on
Receive performance:
a. By default, the driver respects BIOS settings for PCI bus parameters.
However, you may want to set PCI latency timer to 248.
#setpci -d 17d5:* LATENCY_TIMER=f8
For detailed description of the PCI registers, please see Xframe User Guide.
b. Use 2-buffer mode. This results in large performance boost on
on certain platforms(eg. SGI Altix, IBM xSeries).
c. Ensure Receive Checksum offload is enabled. Use "ethtool -K ethX" command to
set/verify this option.
d. Enable NAPI feature(in kernel configuration Device Drivers ---> Network
device support ---> Ethernet (10000 Mbit) ---> S2IO 10Gbe Xframe NIC) to
bring down CPU utilization.
** For AMD opteron platforms with 8131 chipset, MMRBC=1 and MOST=1 are
recommended as safe parameters.
For more information, please review the AMD8131 errata at
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/26310.pdf

---help---
On enabling the 2 buffer mode, the received frame will be
split into 2 parts before being DMA'ed to the hosts memory.
The parts are the ethernet header and ethernet payload.
This is useful on systems where DMA'ing to to unaligned
physical memory loactions comes with a heavy price.
