ok - so you have some link aggregations with 100/1000 and some with 10G adapters. The 10G will almost always be faster. Considering how many 10G ports you have on your box, you may want to consider to move all of them to 10G instead? That would make tuning your network much easier.
If / when you do this, after long and exhausting RAC testing on our systems (similar hardware), we have found below network tunables to be the most beneficial for us. But be careful - do not change all of them at once - but one by one and see if your performance gets better, worse or remains the same.
You can change them via no -p -o name=value - note there is NO space before and after the equal sign in the command to change them.
in addition, you probably want to put this into your /etc/netsvc.conf hosts=local,bind4

I have a network connection problem in unix. I am trying to access to LAN in unix but unfortunately it doesn't work. For example, if I ping from Unix to windows it says 'the network is unreacable'. Also, I can't ping in windows to unix.
I would be glad if someone could help me.
Thanks.

MXGE(4) BSD Kernel Interfaces Manual MXGE(4)NAME
mxge -- Myricom Myri10GE 10 Gigabit Ethernet adapter driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device firmware
device mxge
Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):
if_mxge_load="YES"
mxge_ethp_z8e_load="YES"
mxge_eth_z8e_load="YES"
mxge_rss_ethp_z8e_load="YES"
mxge_rss_eth_z8e_load="YES"
DESCRIPTION
The mxge driver provides support for PCI Express 10 Gigabit Ethernet adapters based on the Myricom LANai Z8E chip. The driver supports
Transmit/Receive checksum offload, Jumbo Frames, TCP segmentation offload (TSO) as well as Large Receive Offload (LRO). For further hardware
information, see http://www.myri.com/.
For questions related to hardware requirements, refer to the documentation supplied with your Myri10GE adapter. All hardware requirements
listed apply to use with FreeBSD.
Support for Jumbo Frames is provided via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility
configures the adapter to receive and transmit Jumbo Frames. The maximum MTU size for Jumbo Frames is 9000.
For more information on configuring this device, see ifconfig(8).
HARDWARE
The mxge driver supports 10 Gigabit Ethernet adapters based on the Myricom LANai Z8E chips:
o Myricom 10GBase-CX4 (10G-PCIE-8A-C, 10G-PCIE-8AL-C)
o Myricom 10GBase-R (10G-PCIE-8A-R, 10G-PCIE-8AL-R)
o Myricom 10G XAUI over ribbon fiber (10G-PCIE-8A-Q, 10G-PCIE-8AL-Q)
LOADER TUNABLES
Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).
hw.mxge.flow_control_enabled
Whether or not hardware flow control is enabled on the adapter. The default value is 1.
hw.mxge.intr_coal_delay
This value delays the generation of all interrupts in units of 1 microsecond. The default value is 30.
hw.mxge.skip_pio_read
This value determines whether or not the driver may omit doing a PIO read in the interrupt handler which ensures that the interrupt
line has been deasserted when using xPIC interrupts. A non-zero value may result in lower CPU overhead, however it may also result
in spurious interrupts. The default value is 0. This tunable has no effect when the device is using MSI or MSI-X interrupts.
hw.mxge.max_slices
This value determines the maximum number of slices the driver will attempt to use. The default value is 1. A slice is comprised of
a set of receive queues and an associated interrupt thread. When using multiple slices, the NIC hashes traffic to different slices
based on the value of hw.mxge.rss_hashtype. Using multiple slices requires that your motherboard and Myri10GE NIC both be capable of
MSI-X. Older Myri10GE NICs can be field upgraded to add MSI-X using the "10G NIC Tool Kit" for FreeBSD which is available from
http://www.myri.com/scs/download-10g-tools.html.
hw.mxge.rss_hashtype
This value determines how incoming traffic is steered to different slices. This tunable is ignored when using just a single slice.
The legal values for this tunable are:
1 Hash on the source and destination IPv4 addresses.
2 Hash on source and destination IPv4 addresses and if the packet is TCP, then also hash on the TCP source and destination ports.
4 Hash on the TCP or UDP source ports. This is the default value.
DIAGNOSTICS
mxge%d: Unable to allocate bus resource: memory A fatal initialization error has occurred.
mxge%d: Unable to allocate bus resource: interrupt A fatal initialization error has occurred.
mxge%d: Could not find firmware image %s The appropriate firmware kld module was not installed. This is a non-fatal initialization error,
but will result in running in a reduced performance mode.
SUPPORT
