Thanks Paul for your help,
So the whole system is slow? This indicates a network/hardware problem. Have you tried replacing BOTH nics in the server?
My system has 2 NICs:
# 1 Intel 100/1000 ethernet NIC onboard for my LAN (internal side).
The Asus install CD comes with the following drivers for linux:
- e1000-5.2.39.tar.gz
- e100-2.3.40.tar.gz
While performing the SME7 install it detects and installs the e1000 driver. Hence no need to manually install the drivers supplied by Asus. As a side note while testing this machine with SME6.0.1 the NIC was not detected so I had to download the dev-tools and install the e1000 driver manually.
# 1 Edimax WOL 10/100 (chipset Realtek RTL 8139D) for Internet (NET side to connect to my Draytek router).
This NIC was automatically detected by both SME7 and SME6.0.1 (driver 8139too).
Although I have one Gigabit NIC on my server my whole LAN runs only at 100Mb (I have not any Gigabit switch yet...).
So, after reading your last post I decided to change the SME7 configuration concerning the NICs: The e1000 NIC/driver becames the NET one (external) and the 8139too becames the LAN one (internal). After rebooting the server voilá!!! Everything rocks!!! Server-manager, proxy/squid, file sharing, etc...
My final question is this:
What was wrong with the e1000 nic/driver acting on the LAN side?This is beyond my understanding. I can't figure this out...
About RAID:
Currently I have 1 RAID1 for SME7 install and 1 SATA disk for data (it will be upgraded to a RAID5 very soon). After analysing the logs (see my other post about HDD configuration) I think everything is running fine.
Also cat /proc/mdstat returned a good healthy raid1
