Hi to all

 

When I transfert files from my share to say.. my computer's HDD on a 100 mbit network, I only got about 9.8 Mb/s of speed. Isnt it slow ? A 114 Mb file take 11-12 seconds to transfert... Should I expect at least 25 - 30 Mb/s ?

 

All is linked by a D-link 624 router

 

What can I do ?

 

My go file looks like this:

--------------------------------------------------------------------------

#!/bin/bash

# Start the Management Utility

/usr/local/sbin/emhttp &

echo nameserver 192.168.0.1 >/etc/resolv.conf

echo 192.168.0.101 fileserver >> /etc/hosts

 

sleep 30

for i in /dev/md*

do

echo Setting $i

  blockdev --setra 2048 $i

  blockdev --getra $i

done

--------------------------------------------------------------------------

I also have attached my syslog...

 

HDParms gives me that:

--------------------------------------------------------------------------

root@fileserver:~# hdparm -tT /dev/sda

 

/dev/sda:

Timing cached reads:  1816 MB in  2.00 seconds = 907.88 MB/sec

Timing buffered disk reads:  244 MB in  3.02 seconds =  80.70 MB/sec

root@fileserver:~# hdparm -tT /dev/sdb

 

/dev/sdb:

root@fileserver:~# hdparm -tT /dev/sdc

 

/dev/sdc:

Timing buffered disk reads:  238 MB in  3.02 seconds =  78.70 MB/sec

root@fileserver:~# hdparm -tT /dev/sdd

 

/dev/sdd:

Timing cached reads:  1708 MB in  2.00 seconds = 853.73 MB/sec

Timing buffered disk reads:  52 MB in  3.02 seconds =  17.19 MB/sec

--------------------------------------------------------------------------

 

Please can someone help me

 

Thank you

I think you meant 9.8 MB/s, not 9.8 Mb/s (MegaByte vs Megabit).  (9.8 Mb/s would be roughly equivalent to 1MB/s.)

 

For a 100Mb/s network, your numbers (and your syslog) look good.  The practical max for a 100Mbps network is around 10MB/s.  Since you have a gigabit card in there, you just need to add a cheap gigabit switch to your current network to gain the 25MB/s speeds (and of course gigabit cards in the desktop machines).  Add this D-Link switch, connect your server and gigabit desktops to it, plus a cable to the 624, and without any config necessary, you'll have gigabit speeds between your workstations and to the unRAID server, with nothing changed on the D-Link 624 and its support for the Internet and any wireless connections.
