Slow transfer speed, Mac 10.4

Hello I'm getting slow transfer speed. It's really slow using the Finder or any another app to connect to the dns323

I've searched and it seems like everyone is having issues because of funplug or whatever hack. But I haven't hacked my dns323 at all.

I'm on a powerbook g4 connected via cat5e cable to a Westell Router (from verizon) and the dns323 is connected to the router as well.

The only thing I have tried is this:
http://www.litman.org/2007-10-08/resolv … s-323-nas/

But with no luck.

Any help would be appreciated

Thanks,

PS I'm using the dns323 to back up my external firewire drive containing my photo library. It is taking more than 24 hours to get 150gigs onto the NAS. I have it set with a static IP address and the speed is set at 1000.  I don't have a firewall going on my mac either.

Re: Slow transfer speed, Mac 10.4

Hello Reydnad,

A while ago I did some speed tests using several settings for delayed ack. This was doen with software version 1.03 on the NAS and using a Mac G4 DA (1,5 GHz) running OS 10.4. All connections 1Gb/s. You can find the results here:
http://www.xs4all.nl/~rloef/Delayed_ack/
In general I feel that changing the delayed ack parameter is of no use. But then, I have no performance issue either.

What speed do you connect to your NAS, 100Mb/s or 1 Gb/s? If one of the components is just 100Mb/s you should still get ~8MB/s throughput.

What OS version is your NAS running? I found that the speed had gone up a little after installing 1.04.

Backing up 150GB in 24 hour would match ~2MB/s. This is indeed a bit slow. That is what my MacBook Pro does while using Wireless-G

Re: Slow transfer speed, Mac 10.4

I think my router is the slowest. I'm not sure what the speed is for that but probably 100Mb/s

the NAS is at 1.03. I'm hesitant to upgrade because I don't have anywhere to back up my data, (at least for the next couple days), in the case that something went wrong.

I'll try that once I have another drive cleared out.

Any other suggestions?

BTW, I did hook it up directly with a crossover connection and it still went slow. it was a little better but not much.

Re: Slow transfer speed, Mac 10.4

First up - if anybody is having transfer speed issues, then fun_plug is NOT the cause - since I run fun_plug and can write at speeds exceeding 170 mbps (measured using SNMP at the network switch)

Next - you say you have the speed set for 1000 and a 100 Mb/s router - that combination WILL give you trouble - better you set the DNS-323 to auto.

Last - backing up 150GB in 24 hours would match ~2MB/s.  This is indeed a bit slow.

Not necessarily - backing up 150 x 1GB files would be quicker than backing up 1500 x 100MB files, which would be quicker than backing up 15000 x 10MB files - I'm sure you get the idea, the mix of file sizes does have an impact.

I can write to my DNS-323 at speeds approaching 180 mbps or 22 MB/sec when it's a single large file - but backing up 13GB of mixed files (roughly 162,000 files) takes me in excess of 18 hours.

Re: Slow transfer speed, Mac 10.4

I am connecting to my dns 323 using an iMac. (leopard 10.5.2).. and I get speeds extremely good speeds.. I can transfer a 1 GB file in about a minute.. I have it connected thru the gigabit port on the router and the router to the gigabit ethernet card on the imac..

works great.. never had any issues.. only when I use stupid windows vista.. the speeds drop for some reason.

Re: Slow transfer speed, Mac 10.4

Firmware on the DNS is truly not the cause of this. You really need to check your local network.

Re: Slow transfer speed, Mac 10.4

I'm pretty sure the slowdown is at my router. Is there anyway I can bypass this? With a hub or something? Or would it still have to go through the router?

Re: Slow transfer speed, Mac 10.4

The only way the router will cause a slowdown is if the data is passing through the router itself - as in from LAN to WAN.

You can bypass the router just use a switch.
