Hello,
We can see
# lspci
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B
PCI Express Gigabit Ethernet controller (rev 01)
I have used a custom kernel to start with centos 5.1 as an initial
installation
Our customer on this kernel has experienced slow pref on samba shares (50
seconds to open a file)
So I have decided to updrade to centos 5.2 that have the right detection of
this card inside (2.6.18-92.1.6.el5.centos.plus)
[<http://wiki.centos.org/AdditionalResources/HardwareList/CentOS5/RealTek/r1
000?action=show&redirect=HardwareList%2FCentOS5%2FRealTek%2Fr1000>]
# yum update
# reboot
The slow samba shares didn't disapear at all !
I have corrected the trouble by doing this :
# cd /usr/src/
# curl -O ftp://218.210.127.132/cn/nic/r8101-1.007.00.tar.bz2
# tar jxvf r8101-1.007.00.tar.bz2
# cd r8101-1.007.00
# make clean modules
# make install
# depmod -a
# insmod ./src/r8101.ko
# reboot
After the reboot we can see that the r8101 module has been activated
# dmesg | egrep -i r[0-9]{4}
Finaly the slow samba share was gone ! (on 10 servers)

If I do an rsync on a LAN, the card holds up to 300mb of data transfer and stops working again. I always have to reboot. No errors, nothing. I have seen many people complaining about this card on the IRC channel too. Miguel -- http://osysadmin.blogspot.com
