Do I need gigabit router for LAN to get gigabit speed if I have gigabit switch.

post #1 of 8
Thread Starter 
I move computers in apt and add htpc, while I was copy files I saw speed of 10 MBytes/s. I did research and people say that normal speed is 100-125 (limit) MBytes/s on Gigabit network.
I run few test with "LAN speed test" software.


After checking my hardware I found that my router limited to 100 Mbps. But after I re-route connection using 1000Mbps switch I was able to triple LAN speed.


Can I do something else without buying hardware? Is 35MB/s my hard drive limit or network?

MY HARDWARE
netgear wnr2000 v2 router
netgear GS605 v4 switch

Edit:
Tests above show speed between my rig and netbook with 5400 HDD
I tested another computer and got better results. This probably proves that I have HDD limit now.

No, you do not.... depending.


If both your 1GbE machines are connected to a 1GbE switch, then the data between them is always at 1GbE.

If one 1GbE machines are connected to a 1GbE switch and another 1GbE machine is connected to a 100Mbps router and the router is connected to the switch., then the data between them will be limited to 100Mbps.

I assume no wifi being used to connect the machines here?

The connection will be at best only as fast as the slowest part between 2 points. As the other poster pointed out, if its from GBe to GBe across the switch, then youll get the gigabit speed. But if you have the router in between 2 computers then you get the lower speed.

So if you require the full speed, then you ideally want something like the below setup. If your internet is lower then 100MB/s then the router will serve just fine for internet access. The gigabit connection will only benefit you in file xfer between computers on your internal LAN

Modem -> router -> switch -> all computers

If you cannot setup all computers on the switch and need some wired to the router or if your home internet is faster then 100MB/s (unlikely), then you need a new router with gigabit.

...Or he can get another 1GbE switch for $20 and connect that to the other switch.

8 bits in a byte, 100 mbps = 12.5 MB/sec not considering overhead.

I did test with main rig (with SSD) and asus N10j netbook with 160 Gb 5400 rpm HDD.



LOL, my internet is 18 Mbps - 2.25 MBps

Yea yea tongue.gif the perils of posting from work.

Also as someone else pointed out another switch may be an option if your current config doesn't allow all of the hard wired computers to be on the current switch.

Personally if money isnt too tight id say get a new router. For under $100 you can get a newer router with gigabit built in and possibly faster wifi too. Aside from that you may be able to get a router with extra features that may prove useful like USB port for storage devices (simple NAS), torrent client, multiple SSID's, guest network, etc. Ive also found that the more network devices you have the more difficult troubleshooting becomes.

I doubt that your network is bottle necked by the speed of the HDD's. Running ATTO or something on the drives should shed light on their speeds. My WD Reds and Seagate 7200 rpm drives both hit ~150MB/s read/write. My gigabit connection on large files runs a steady ~112MB/s
