Hi,
i hope someone has a clue on that.
When i trying to copy data from an OSX Client over AFP to an Archlinux Server the network stops for a while. Look like the System has to write a cache or so first.
I also tried some other components. What has never change is the Switch, Mainboard and ext4 on the RAID. When i am using FreeNAS with UFS everything runs fine.
Actual configuration:
2.6.36-ARCH
Netatalk from AUR
3Ware 9500 LP RAID 5 with 4 WD Green 2TB (formatted as ext4 and GPT Partition Type)
Networkcard Intel Pro 1000 MT Dual Server PCI-X (two different IP's by DHCP)
Board ASUS P5WDG2 WS Pro
