Aggregation 4 gigabit ethernet low speed

Hello
I've got a Synology DiskStation DS3612xs (Ultra-high performance of 1000+ MB/sec throughput and 100,000+ IOPS)
connected to my MAC PRO with 4 gigabit Ethernet connection with Link Aggregation,
and I only got 233.9Mo/s
the same performance with dual gigabit link aggregation.
What am I doing wrong to get the same speed result with 2 link aggregation than with 4 link aggregation ??
is this a apple bug ?

no the 4 link aggregat by apple is not fast enough.
if I have to different computer connected to my DiskStation via 2aggregat ethernet
each computer got 233.9Mo/s speed.
but when I connect only one computer via 4aggregat ethernet : I got only 233.9Mo/s speed
BUT I should have the +/- 466 Mo/s speed as I got with the 2 different computers insn't ???
Please help.
Thanks anyway

Mac Mini Server Link aggregation - Thunderbolt or USB 3 gigabit ethernet adaptors

I am setting up a late 2012 Mac Mini as a file server with Server 2.2. It has a Promise Pegasus R4 RAID and LaCie 4TB drives daisy chained via the Thunderbolt connection. 4 users on MacPro's will connect to the server to access these hard drives via gigabit ethernet.
I imagine the gigabit ethernet will be the bottleneck, so I'm now looking at link aggregation. Not a problem on the MacPro's but the Mac Mini will require an adaptor to get a second gigabit port. From reading this forum I understand the Apple Thunderbolt to Gigabit adaptor will work, but I'm concerned that it will need to be fitted 3rd in line after the R4 and LaCie drives. The 10Gbps bandwidth Thunderbolt has, may cause another bottleneck with all three working off the same port?
An option would be to use one of the USB 3 ports with this adaptor http://www.ebuyer.com/412005-startec...edium=products
I believe it work with OSX, but I have no speed information or if OSX link aggregation will work using it.
Any thoughts on the above would be appreciated and recommendations on a suitable Network Switch with LACP support welcome.

At present Mountain Lion Server cannot use a LACP bond, in my experience only of course. http://www.small-tree.com/kb_results.asp?ID=59 describes LACP/Bonds do not show up in Server Admin GUI on Mountain Lion
anyone know how to do it? or the location and the name of the plist file to configure the network interface in ML server?

IMac i5 27" - gigabit ethernet speed slooooooow

I know there are other (older) threads about this (https://discussions.apple.com/thread/2236017?tstart=0) but I thought I'd start a new one.
I have just purchased an iMac i5 27", and find that plugging it into my Netgear GS605 gigabit ethernet switch doesnt work as expected. My older 24" iMac works as espected, just fine.
I am able to get a gigabit connection (green light on switch) and if I try to copy large files form another Mac or my Lacie 2Big Network 2 NAS it works fine. BUT, if I then try to surf the web, my download speeds are ridiculously low (should be 30MB/s, getting 0.4)??
If I manually downgrade the ethernet controller settings to 100B/T, the internet speed works just fine, but obviously local transfers are then crippled to fast ethernet speed, which on a 200GB Time Machine backlup isn't much fun!
I have had many conversations with Apple Support, and returned one of these iMac's already, to find the next one does the same thing - all very frustrating.
So is there a fix? Can the Broadcom chipset be to blame? Is it to do with Jumbo frame support (whatever that is) - the Netgear switch supports it, but not sure about the iMac, and why does the internet speed drop so dramatically, when the file transfer speed works as expected over gigabit ethernet?
Grrrrr. Really frustrating I can't have high speeds on both types of transfer.
Any help gratefully received!

How do I maximize LAN speeds using Gigabit Ethernet, jumbo frames?

I move a lot of large files (RAW photos, music and video) around my internal network, and I'm trying to squeeze out the fastest transfer speeds possible. My question has to do both with decisions about hardware and what settings to use once it's all hooked up.
This is what I have so far:
-- imac 3.06GHz, macbook pro 2.53GHz
-- Cisco gigabit smart switch capable of jumbo frames
-- Buffalo Terastation Duo NAS (network attached storage), also capable of Gbit and jumbo frames
-- All wired up with either cat6 or cat53e.
-- The sizes of the files I'm moving would include large #s of files at either 15MB (photos), 7MB (music), 1-2GB (video) and 650MB (also video).
-- jumbo frames have been enabled in the settings of the macs, the switch and the buffalo HD.
-- I've played with various settings of simultaneous connections (more of a help with smaller files), no real difference
-- Network utility shows the ethernet set to Gbit, with no errors or collisions.
-- have tried both ftp and the finder's drap and drop
-- also, whenever I'm doing a major move of data, I kick my family off the network, so there is no other traffic that should be interfering.
Even with all that, I'm still lucky to get transfer speeds at 15-20mbps, but more commonly at around 10. The other odd thing I've encountered while trying to up my speeds, is that I might start out a transfer at maybe 60mbps, it will maintain that for about 30-60sec and then it appears to ramp itself down, sometimes to as low as 1-5mbps. I'm starting to think my network is mocking me
I also have a dual band (2.4/5) wireless n router (not jumbo frame capable), but I'm assuming wired is going to trump wireless? (NOTE: in my tests, I have disabled wireless to force the connection through the ethernet).
Can anyone help with suggestions, and/or suggest a strong networking reference book with emphasis on mac? I'm willing to invest in additional equipment within reason.
Thanks in advance!
juliana

I'm going to pick and choose to answer just a few of the items you have listed. Hopefully others will address other items.
• This setup was getting me speeds as high as 10-15MB/sec, and as low as 5-6MB/sec when I was transferring video files around 1-2 GB in size
I would think a single large file would get the best sustained transfer rates, as you have less create new file overhead on the destination device. It is disturbing that the large files transfer at a slower rate.
• Would a RAID0 config get me faster write speeds than RAID1? I have another NAS that can do other RAID configs, which is fastest as far as write times?
RAID0 (Striped) is generally faster, as the I/O is spread across 2 disks.
RAID1 is mirrored, so you can not free the buffer until the same data is on BOTH disks. The disks are NOT going to be in rotational sync, so at least one of the disks will have to wait longer for the write sectors to move under the write heads.
But RAID1 gives you redundency. RAID0 has not redundency. And you can NOT switch back and forth between the 2 without reformatting your disks, so if you choose RAID0, you do not get redundency unless you provide your own via a backup device for your NAS.
• what is the most efficient transfer protocol? ftp? smb? something else? And am I better off invoking the protocol from the terminal, or is the overhead of an app-based client negligible?
Test the different transfers using a large file (100's of MB or a GB sized file would be good as a test file).
I've had good file transfers with AFP file sharing, but not knowing anything about your NAS, I do not know if it supports AFP, and if it does, whether it is a good implementation.
If your NAS supports ssh, then I would try scp instead of ftp. scp is like using cp only it works over the network.
If your NAS support rsync, that would be even better, as it has the ability to just copy files that are either NOT on the destination or update files which have changed, but leave the matching files alone.
This would help in situations where you cannot copy everything all at once.
But no matter what you choose, you should measure your performance so you choose something that is good enough.
• If a client is fine, does anyone have a suggestion as to best one for speed? Doesn't have to be free -- I don't mind supporting good software.
Again just test what you have.
• Whats a good number to allow for simultaneous connections, given the number of files and their size?
If the bottleneck is the NAS, then adding more I/O that will force the disk heads to move away from the current file being written will just slow things down.
But try 2 connections and measure your performance. If it gets better, then maybe the NAS is not the bottleneck.
• What question am I not asking?
You should try using another system as a test destination device in the network setup to see if it gets better, worse, or the same throughput as the NAS. You need to see about changing things in your setup to isolate where the problem might be.
Also do not rule out bad ethernet cables, so switch them out as well. For example, there was a time I tried to use Gigabit ethernet, but could only get 100BaseT. I even purchased a new gigabit switch, thinking the 1st was just not up to the task. It turned out I had a cheap ethernet cable that only had 4 wires instead of 8 and was not capable of gigabit speeds. An ethernet cable that has a broken wire or connector could exhibit similar performance issues.
So change anything and everything in your setup, one item at a time and use the same test so you have a pear to pear comparision.

What's the maximum LAN speed with the Thunderbolt to Gigabit Ethernet Adapter on my MacBook Pro?

While I was at Yodobashi Camera yesterday, I got a Thunderbolt to Gigabit ethernet adapter for my MacBook Pro. I figure, since I'm paying for the high speed fiber optic (Sony Nuro), why limit my self to wi-fi speeds at home?
Before connecting the adapter, via wi-fi it the speed was 143.8 Mbps down and 181.5 Mbps up.
After connecting the adapter and making a direct LAN connection to the router, the speed is 783.2 Mbps down and 940.1 Mbps up.
I'm certainly happy with the speed, but since Sony Nuro is supposed to be 2 Gbps down and 1 Gbps up I was wondering what the maximum possible is with this computer and adapter. Before asking the provider I was curious what the maximum specs where.
The ether cable is a 3 m category 6.
Thanks,
doug

It's not really your computer that is getting the 2Gbps download - it is the router/ modem.
If you hooked better/ different hardware up you could probably push those speeds around your network too. The trouble is that most residential hardware is gigabit ethernet not fibre. Fibre cards & cable are expensive in comparison.
The existing hardware may allow you to 'bond or aggregate' multiple ethernet connections into one link to get more speed over ethernet. Obviously this requires more complex routers, switches & a network admin to set it up
Those speeds sound nice, this bottleneck will mean that other devices on you network can't choke up the whole connection & make other users sad.

Problem speeding up to gigabit ethernet

Hello,
Hopefully someone here will be kind enough to help me out with this one...
Im trying to set up a gigabit ethernet network with my PowerBook G4 12" 1.5 GHz, a gigabit switch, and an iBook G4 1.2 GHz. The problem is that when I connect everything together I only get 100baseTX speeds max. On both the iBook and PB if I go into Network Preferences and configure ethernet speed Manually (Advanced) it only shows autoselect, 10baseT, and 100baseTX. No 1000base...
I have tried multiple cat 5e and 6 cables, all known good.
I have also tried the setup without the gigabit switch (ethernet cable between the two computers) and still get the same result.
Oh and both systems are running 10.4.7
Any help with this would be very much appreciated.
Thanks in advance!
PowerBook G4 1.5 GHz, a gigabit switch, iBook G4 1.2 GHz Mac OS X (10.4.7)

No problemo. At least now you won't be tearing your hair out trying to figure out why you can't get the data moving any faster. Happy 4th.

What file transfer speeds are possible over Gigabit Ethernet - Hatter?

Thanks in advance for taking the time to consider this.
Our still photgraphic studio has a range of MACs all connected via a gigabit D-Link switch to a series of Buffalo NAS raids. Wiring is CAT5e, all devices have gigabit ethernet cards and the link lights on the switch suggest that all devices are connected at that speed.
We currently get file transfer rates of between 5 and 12 MB/s depending on network traffic.
We would like to upgrade our NAS to a NAS/SAN, preferably using the existing wiring (and avoid the expense of Fibrenet). 50 or 60MB/s would be great if possible.
Any ideas for a suitable archtecture and Hardware would be gratefully received. Cable lengths are a maximum of 30 metres.
Paul

I'm getting sustained speeds of 90-100 megabytes/second on a transfer across GigE from one mac to another, both working on high-capacity SATA drives.
It drops to ~65 megabytes per second if the source drive is my 2TB Firewire 800 external.
both rates are right on the real-world maximum for GigE and FW800 respectively, which is a great sign that nothing else is bottlenecking the transfer.
My experience with NAS boxes has been disappointing in the past, with transfer rates of 5-35 MB/sec - painfully slow for large files, which destroys the purpose of NAS for me, which is reasonably high-speed off-computer storage.
I'm MUCH happier, and didn't have to pay very much to set up a Mac with 4 SATA drives onboard, acting as a file server... I'm actually getting files FASTER than I am from a FW800 drive directly attached now.

Not getting full Gigabit Ethernet Speed on iMac Core Duo

I am using Airport to connect to a Linksys Wireless Access Point connected to my DSL modem. I am using ethernet to connect to a 3Com OfficeConnect 8-port Gigabit switch. I have 2x 500 GB LaCie Ethernet Disk Mini's (with Gigabit interface) connected to the switch.
The lights on the switch tell me that the drives and iMac are connected at full speed, however I can transfer a 650MB .dmg file to a firewire 400 drive in 1/4 of the time it takes to transfer the same file to one of the gigabit ethernet drives.

I have no idea what that all means, but i do know that I am not getting gigabit ethernet speed.
Can anyone help?
Thanks

If you are transferring data via wireless then you cannot approach Gigabit Ethernet speed. 802.11g has a maximum transfer speed of 54 Mbps while 802.11n is about 130 Mbps. This is much slower than a FW400 port. Your router and switch must both be Gigabit capable and your drive must be connected to Ethernet to even hope to achieve Gigabit speeds - no wireless.

Using both Dual Gigabit Ethernet Ports

Using both Dual Gigabit Ethernet Ports
If I plugged both of my ethernet ports into my LAN switch, that would double the bandwidth to and from my machine. A switch does not used shared bandwidth like a hub does. I realize that it won't speed up any of the other devices that are plugged into the switch. Regardless, I would have the capacity for double the bandwidth to my machine.
All LAN cables are CAT6 and the switch is 10/100/1000.
The question is, would Mac OS X 10.4.7 utilize both ports (soft of the way it uses multiple processors)?

It's easy to try... it's call "Link Aggregation"...
http://docs.info.apple.com/article.html?artnum=304120
You get to it by Network>Show>Network Port Configurations>New then Port in the popup, then you schould see Port Aggregation. Selt the two ports you wish to combine.

Slow internet connection with gigabit ethernet?

I have a 1Gbps (1000Mbps) internet connection from my ISP, using the internet speed testing service provided by local authorities, my internet download speed is shown to be at least 250Mbps (close to the max limit of the test) when my iMac directly connected to my wall ethernet socket.
However, when Mac is connected to the internet through my 2012 Time Capsule (all ethernet and time machine disabled), my internet download speed is slowed to 96-98Mbps.
I understand that all ethernet ports on the 2012 spec Time Capsule is gigabit ethernet, and I have checked my connection using the network utilities, which confirms that my linkspeed is 1Gbps. The hardware tab on my Network preferences also shows that my ethernet is set to 1--base T, full-duplex.
So where did the 60% speed decrease come from?   Is this ~96-98Mbps speed limit a hardware limitation? Or is my time capsule set up incorrectly?
I understand that similar questions might have been posted in the forum before, but I haven't b thread with the exact issue I described above.   Any help would be appreciated.

Many thanks for your incredibly detailed reply. All the information in your solution is correct, and while it did not directly solve my problem, it would have taken my a lot longer to figure out the issue without the information you provided.
I didn't realize we're missing so many functions in airport utility 6.0.
Anyways, upon reading your advice, I installed Airport utility 5.6 on mountain lion and checked the link speed settings.    Apparently it was automatically set to 100Mbps when connected to my cable modem.
Strangely, if I manually change the link speed to 1000Mbps full duplex, Time Capsule would report an "ethernet unplugged" error along with the consequential "internet connections" and "no DNS servers" error.   Since my ISP has been supporting consumer 1Gbps internet for a few years now, and since I am able to get an over-100Mbps actual link speed with directly connection to my cable modem, I am certain that my cable modem connection supports 1000Mbps local connections.

You're also correct in that Time Capsule does not have a settings for "half duplex" for 1000Mbps link speed. But hooking my my mac directly with my cable modem, Mac network preference pane reports that the 1000Mbps connection between my mac and cable modem is full duplex, so my ISP does allow full duplex 1000Mbps connection.
After NUMEROUS tests, I discovered the problem is down to a FAULTY ETHERNET CABLE, which I did not use for my Mac -> cable modem direct connection. This was why I was able to get gigabit ethernet speed with a direct connection but not through time capsule!
I replaced the faulty cable with a new cat-6 ethernet cable and voila! problem solved!
So here're the test results (using an more up-to-date speed test) before and after I replaced the faulty lan cable:-
(while I'm at it, I've also thrown in some additional results demoing the wired and wireless throughput of the 4th gen Time Capsule)
Faulty cable through Time Capsule:-
New ethernet cable direct connection:-
Wired connection through Time Capsule:-
Wireless Connection (wireless-n 5GHz three streem 450Mbps transmit rate) through Time Capsule:-
I'm a bit surprised that a damaged cable resulted in a lower link speed rather than no connection at all.
Also, while the throughput of Time Capsule can't really match the link speed of the direct connection, I'd say it's not shabby at all.
Thanks again LaPastenague for your solutions.

Gigabit ethernet + TC doesn't mean gigabit transfer rates to the TC drive..

Alright.... I've spent a ton of time trying to figure this out (probably more than I should have) and I thought I'd post my findings so that either a) I'll save someone else time out there or b) someone can tell me I'm a complete moron
So I had an airport extreme. I replaced it with a Time Capsule. I have a Windows (boooo) PC connecting directly to my TC using a gigabit ethernet card (which I bought specifically connect it to the TC) so (I thought) I could enjoy gigabit transfer speeds to the internal hard drive from the wired PC. I had some fun plans of shoving my itunes directory on the TC and letting appletv sync (yes through my pc) and keeping lots of videos there, etc. Who cares - it'd be at gigabit speeds! But, in reality, things didn't quite work that way (though my itunes directory does still live on my TC...for now).
Well, I had a semi-unique situation to do some pretty massive testing because I have 2 gigabit network cards, 1 100mb network card, and a wireless-n network card and two internal hard drives - both very fast. I also tried Cat 5, Cat 5e, and a Cat 6 cable.
And here's what I (think I) figured out:
The hard drive in TC can not achieve gigabit transfer speeds. Your transfer rates will be limited by the IO to the hard drive. In fact, it can't even come close.
Using my "fastest" setup - so Cat 6, fastest internal drive, gigabit ethernet, and transferring a file exactly 1 gig in size I was able to have a sustained transfer rate of 140 megabit per second - that's 17.4 MB/s for folks not wanting to do the math (that's reading FROM the TC. Writing TO the TC dropped the speed down to 106 megabit/second or 13.35 MB/s). Going to a 5e cable knocked that down to 130 megabit a second. Putting in a Cat 5 cable knocked me down to 110 megabit a second. Switching between my two gigabit network cards did nothing. Switching my cards between two computers did nothing.
Now, just changing the above setup to use my 100Mb network card resulted in these results: 67 megabit read (8.4MB/s) and 65 megabit write (8MB/s)...
And using wireless N, I got about 10MB/s up and down.
And just as a final test, connecting my two computers together using the 2 gigabit network cards through the TC, I was able to achieve standard gigabit speeds.
SO what does this all mean?
I think the IO to the hard drive in the TC can only read at about 140 megabit/s and write at about 110 megabit/s. I'm not sure if it's the HD itself or how it's connecting to the TC - but that's why I'm not aware of anyone getting faster transfer rates to the drive in the TC (maybe you guys are?). The gigabit ports themselves are fine - and if you're doing anything from one gigabit port to another gigabit port you'll be fine.
So stop beating yourself up trying to find some elusive XP specific issue with gigabit transfer rates (though vista had a problem - shocker), or that you must have a defective gigabit card (which is why I have two cards now instead of one :)), or that your cable must be bad ("maybe my cat 5e isn't good enough?")... it's just this drive ... or how the drive is connecting to the network - can't handle the gigabit speeds.
Unless someone else out there has another explanation? Do these speeds mesh with what you're seeing in "optimal" situations? Or maybe there's just a throttle switch for goobers like me using Windows instead of MacOS!

Hi,
the interfaces available today which connect your drives integrated electronics to your computer can handle that speeds. but the drive itself is limited by the mechanical things going on in there
You can get such transfer speeds if the data you request is in the cache of the drives internal electronics for example. Some drives have 8 MB of cache memory. So if you request to read or write less than 8 mb and (in the read case) you are lucky enough to have those few megabytes cached then you may get that performance

Airport extreme (gigabit ethernet) b/g not working

I have an airport extreme (gigabit ethernet) that I use as my base in an extended network. I Have always had it in Wireless N mode with b/g compatability. the other day my speeds went from being super fast and happy to less than 1mbps. I went and plugged directly in to the airport via ethernet and got blazing fast speeds again.. I switched my radio mode to n only and wireless speeds were fast again.. switched back to b/g compatible and they are in the toilet.. is it possible for the b/g compatible antenna to just crap out? if so this is very disoncerting as I have several wireless devices in my home that operate on b/g and don't want them to be left out in the cold.
Any input is greatly appreciated.

what I did with the b/g testing was I changed the name of the base station to another name so none of the b/g devices that were connecting to it could.. and so it was only the laptop I was using to run the tests.. and still the speeds were terrible.. of course then when I changed it to "n" only mode they were fast again. so I know that my laptop was the only client connected wirelessly or otherwise to the base station when running both tests.
I am extending the network with an airport extreme base station dual band. The solution I have in place currently is to basically swap them. I Have the Dual band running as the main base station in N mode with b/g compatability, and I have the Gigabit ethernet AEBS running as the extender... so far my speeds haven't suffered at all and hopefully it will hold that way. but I still can't understand why the AEBSn would suddenly just stop providing any kind of speed when running as the base in b/g compatibility mode.

Thunderbolt to gigabit ethernet problem

On my new Macbook Air (Intel Core i7) I'm trying to connect to my office network using a Thunderbolt to gigabit ethernet adapter, but the network system preferences say that the cable is unplugged. Any suggestions for how I can go about checking what's up?
Many thanks,
Adriaanh

I had this probem also in 10.9.
I was selecting Thunderbolt 1 from the dropdown list of interfaces.
It took a while to realize that Thunderbolt Ethernet is actually the correct option, lower down in the list.

How to tell if my netbook has gigabit Ethernet (and/or can use it)

I have owned an Asus Eee 701SD (the 8GB version) since 2009, and installed Arch on it last summer (a great move :-) ).
The other day, I came across a page on the FreeBSD wiki, which suggested that certain 700-series Eee's have a gigabit Ethernet interface (rather than the usual 10/100). Through checking 'hardinfo' and 'sudo lshw -c network', it appears that my machine might have a gigabit interface, but I'm not sure. This is the output from lshw:
*-network
description: Ethernet interface

This is a bit confusing - the "capacity" heading above indicates the Ethernet is 10/100, but the Atheros Ethernet interface is given as "AR8121/AR8113/AR8114 Gigabit or Fast Ethernet" (confirmed by 'lspci'), which I guess means it can act as either gigabit or 10/100.
Assuming that all this means I do have a gigabit Ethernet port on my netbook: will the Arch system make automatic use of the extra speed, or do I need to issue any commands, change any settings, recompile the kernel, etc.?
Many thanks :-)
Tim

If it were a Gigabit NIC, it would simply be "AR8121/AR8113/AR8114 Gigabit"
Seriously, if the driver is working properly, 100Mbit/s is what you have got. You can check again with
ethtool eth0
which lists the supported device speeds.
