NASLite+ transfer speed max only 8Mb/sec

pszilard · **Posted:** Fri Oct 14, 2005 6:34 am

I am using NASLite+ 1.4 on a 1.8GHz Pentium 4 and 100 mbit LAN. All configured and booting off CD, but I still cannot get any speed above 8 Mb/sec. The HDD is a 20GB drive, one only. Read and write are about the same speed.

What should be the achievable max speed?

What could be the reason for my slow speed?

Thanks in advance,

Here is the syslog:

Could the speed limit be related to the nic I am using?

I also tried a Netgear 10/100 nic but it wasn't recognized. Should it have been?

Would the NASLite+ Gig version work with a 10/100 card, or must it have a Gig nic?

My LAN is 100, but would there be any advantage if I installed a Gig nic on a 100 network? Would that give higher speed when using NASLite+ G?

Any help would be much appreciated...

Hi Paul,

What transfer speed are you looking for?

One thing to consider is that with SMB/CIFS transfers, all you could really expect is 65%-70%. FTP is considerably lighter in that respect and consistently produces transfers at 90%-95% on my 10/100 network.

pszilard · **Posted:** Fri Oct 14, 2005 9:58 am

Hi Tony,

I was hoping for at least 50% of the theoretical max of 100 Mbps, instead of the 8% (8 Mbps) that I am getting. My numbers are for bit/sec not bytes/sec. i.e. I am getting only 800 kBytes/sec.

Can you tell me what is a realistic expectation and how to achieve it?

Thanks.

Tony · **Posted:** Fri Oct 14, 2005 10:19 am

(8 Mbps) is too slow, so something is not right. In the syslog info page, you should see a line similar to this:

Code:

Oct 4 09:15:15 STC-4 user.info klogd: eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

It will tell you what the NIC negotiates with the network. I don't see it in your post above, but one should be there.

You can unplug the network cable, wait 5 secs and plug it back to generate the event. Then wait 6 minutes for the Info pages to refresh and take a look then.

That will be a start.

Another thing Paul,

I'm not sure but I think the RTL-8029 is 10T and not 100T.

Problem solved? the RTL-8029 is infact 10T only..

here is a link with the card specs.

if you want a new network card you can check the NIC cards other users of naslite have used here http://www.serverelements.com/phpBB2/vi ... 064980b75d

I use a Netgear FA311 10/100 works fine.

pszilard · **Posted:** Fri Oct 14, 2005 6:59 pm

Thanks for the helpful replies. I have another nic which says Netgear on it, but I can't tell the p/n as it is not marked. NASLite+ doesn't seem to like it and says it can initialize adaptor.

As nics are cheap, I'll just get another one to try next week. Once it works, I'll report back on the results. Thanks again.

pszilard · **Posted:** Fri Oct 14, 2005 9:59 pm

Well, I have to apologise as what I thought was a Netgear nic wasn't. It was just in a Netgear cardboard box in my garage! I just bought a real Netgear FA311 (Au$17), plugged it in and Hey Presto! speed is now peaking at 78 Mbps and averaging 75 Mbps.

FANTASTIC! I am happy and I shall try to return my Netgear SC101 SAN which is only running at 1/4 the speed of the NASLite+.

THANKS Tony for making NASLite+ and to all who assisted

I am using NASLite+ and it is good and very fast but have just installed a Netgear SC101 for the mirroring althought it is slow due to the software raid being a 'write twice' arrangement.

I use NASLite+ for the ripped DVDs / music etc and the SC101 mirrored 250GB for the family photos family videos. Seems a good combination for the critical data

Regards,

Jason

pszilard · **Posted:** Mon Oct 17, 2005 8:44 am

Interesting. I also have an SC101, and have 2x200GB in it in span mode. I am undecided between NASLite+ and SC for use as my 2nd backup of a RAID 5 array of 4x 200GB. I am leaning towards NASLite+ as I can upgrade that to Gig lan and can just have 2x NASLite+ servers and just backup to both, over night. Kinda "poor man's mirroring"

With my NASLite+ having 2.5x the speed of the SC, it is still faster to do two sequential backups than one single one to the SC - that with the SC not in RAID 1.

What write speed do you get on the SC in RAID 1 mode?

Jcoyne · **Joined:** Wed Sep 21, 2005 4:40 am **Posts:** 9

In raid 1 the sc101 is flat out at 24-25% of a 100mb network from the xp network task manager (I dont know what this equate to - sorry) when writing and about 45-50% when reading. The NASLite reaches 85% read and write

regards,

Jason

pszilard · **Posted:** Tue Oct 18, 2005 10:07 pm

Well, for testing, I converted my SC to mirrored. I am getting write speeds of 2 MBytes/sec which results in around 20 Mbps nic traffic. Read speeds are about twice as fast.

As my original data is on a RAID 5 array, I have decided to send back the SC and put the two 200GB disks in a NASLite+ server, where I can get 8 MByte/sec read/write speeds

NASLite Network Attached Storage

NASLite+ transfer speed max only 8Mb/sec
