Anyways, I have a D-Link DGS-108 Gigabit switch, which supports jumbo frames.
Since my home seedbox uses an atom cpu (GA-D525TUD with a realtek nic, transfer speeds to my NAS were far from great. (around 30MB/sec, while transferring the same file from windows PC to NAS could easily achieve 60-65MB/sec)
So I thought what the hell let's try jumbo frames to see what happens.
So, changed MTU of windows to 9K, seedbox to 9K and wanted to do the same on n4f. So wrote 9000 in the mtu setting, save, asked me to reboot and after reboot, ifconfig shows this:
Code: Select all
$ ifconfig nfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=82008<VLAN_MTU,WOL_MAGIC,LINKSTATE> ether xx:xx:xx:xx:xx:xx inet 192.168.1.102 netmask 0xffffff00 broadcast 192.168.1.255 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect (1000baseT <full-duplex>) status: active
Tried to write mtu 9000 in ifconfig extra options, but still the same.
FreeBSD manual reports that jumbo frames are supported unless I get something wrong...
This is the motherboard I have (also in my sig): MSI GF615M-P33
While in there it says that the NIC is a Realtek 8211CL, n4f reports my NIC as nfe0, (and msi website states that chipset is nforce 430) so that's what I searched for (besides the fact that I cannot find anything about 8211cl in the manual)
Mind you I am still in n4f version 188.8.131.52 - Sandstorm (revision 847)
Any ideas welcome..!
