Mac Forum / General / Hardware / February 2006Extremly Slow network share on G5 quad setup.
Greetings, I have a G5 Quad that I have a file share on that my wife's G5 quad connects to (It has MP3's on it for example). We are connected to each other via a Airport extreme. I checked and it seems to be running at the full 54 Gb. But the file transfers and finder windows to that share are _extremely_ slow. It took 8 hours to copy 10 GB. And when she syncs up her IPod that is pointing towards the share it takes 1 hour or more to sync up 400 songs. Also when she looks through the finder windows and just tries to copy files it is very slow. Nowhere near the speeds we see when we our windows boxes doing the same thing. Directory changes seem to take several seconds (4 to 5 at least) I have tried both with AppleTalk and without and there does not seem to be that much difference in speed. Since I am fairly new to the Apple world, I am not sure where I might have messed up in the configuration or setup. I am very familiar with the Unix environments. Anybody have any suggestions to what I could check? We are both running 10.4 with all the latest patches. My machine has 4 GB Ram and hers has 3.5 Gb. The drives she tries to work on is on my master bus and is my second hard drive in the system. (Not my primary hard drive) No raid or any special configurations for the drives. Thanks, Hank. > Greetings, > > I have a G5 Quad that I have a file share on that my wife's G5 quad > connects to (It has MP3's on it for example).

Network and packet overhead reduce that to around 30Mps, give or take a few. > But the file transfers and finder windows to that share are _extremely_ > slow.

Filesharing over 802.11g is slow - why on earth don't you use Ethernet for this? Or get 4-pair CAT5 and run at 1000Mps. Sorry but sharing lots of data over wireless is plain daft. Chu  Signaturechuenginsberg at mac dot com Although I appreciate your mostly useless response, It does not help me with my problem. I would put in cat5, but since I live in a rented place I can not put the cables away nicely. The fact of the matter is that I see transfer rates of less than 500kb a second. I see transfer rates from the internet over the same network at a higher rate. (tripple if not more on a bad day) I should see transfer rates of several Mb a second. Less than 500kb a second is not acceptable. Thanks though. Hank. Hi Hank, We run most of our company over wireless. You are correct... the transfers should be much faster. At the theoretical peak, the Airport Extreme (802.11g) is 54 Megabits per second, you are looking at best case of 2.4 gigabytes an hour. This is about 5 times faster than the earlier Airport (802.11b) cards. For reference, Fast Ethernet is only 10% faster than 802.11g (60 Mbps vs. 54 Mbps). See: http://www.forret.com/tools/bandwidth_real.asp for some real world benchmarks. Wireless does have additional overhead which does slow the transfer... a little. The drawback of the 802.11g though is variable speed dependent on signal strength A weak signal (longer range) can drop the transfer rates all the way back to standard Airport ranges. If you have "four bars" in your signal icon on the menu bar (assuming you have set the Airport/Network to show the status in the menu bar), then range is not the issue. If it is range, then you can boost the signals with various products. See: http://daystar-store.com/index.asp?PageAction=MFGSEARCH&ManfID=11 An easy test to see if the wireless is the culprit, if to connect via ethernet (you will need a crossover cable to connect direct from system to system, or regular if connecting both to your router). If the transfer is normal rates, then you have a wireless issue. Check your systems via your wireless router to the internet to see if you may have a bad card in one of the systems. It may also be simply a software problem. Try creating new accounts on the systems and checking. Also, check any anti-virus stuff you might have running in the background. If you are running one of your systems in the "create network" mode, it can slow down transfers. You can also try going into the Network preference and create a new location. This will help blow out any corrupt settings. Last, if you are running an open wireless network, someone may be sucking your bandwidth. Sorry, but it is difficult to troubleshoot without more info. Basically you either have a hardware, software or range issue. |
