LAN Networking

[MacBook1]

I have a Trendnet TEG-S80g Ethernet Switch. Connected to this is four computers (two of which are NAS servers running nas4free) and a router. Connected to the router is my Mac Pro and gaming PC. The router has DD-WRT and bridges to the main wifi router. I am currently getting pretty slow transfer speeds between the NAS servers and Mac Pro/gaming PC. Does anybody have any suggestions for speeding it up? The switch and my main computers support Gigabit but the router and servers will bottleneck it anyway.

what speeds

 

what iperf speeds do you get

What is the "slow speeds", are they connected using CAT5E or 6 cables? because I find one of my lan cables to my laptop was just standard CAT5.

The cable between the Mac Pro and router is CAT5e. The cable between the router and switch is CAT5 and the cable between the NAS and Switch is CAT6. The Read and Write Speeds are both 7.6 MB/s according to the HELIOS LanTest. I don't know how to use iperf. I get the error "iperf3: error - unable to connect to server:".

Why is router to the switch CAT5 cable? is your internet slower than 10mb/s? even than the cost of CAT 5e to 5 is only a few cent. 

 

There is your problem as the nas is connected to the switch, I would get new cable and replace that CAT5 cable with CAT6 or 5e.

I replaced the cables with CAT5e. (Turns out the one between the router and Mac was just a CAT5.) Now it goes NAS4Free>CAT6>Switch>CAT5e>Router>(wifi?>main router?> wifi?)>CAT5e>Mac. I am getting about the same speeds for before the new cables and after.

Is the NAS and the MAC connected through the switch? If the MAC is connected to router that may be the issue.

No, the mac is not connected to the switch. It is connected to the same router that the switch is connected to though.

Without knowing how your network looks, my guess is that the problem is one of these things:

1) You are on wireless somewhere, and your wireless is slow for one or several reasons. Use cables whenever you can.

2) You are limited to 100Mbps somewhere, which translates to ~10MBps (which is very slow for local file transfers). The only thing to fix this is to upgrade your hardware so that it is gigabit everywhere.

3) You are transferring files which are just hand for your devices to handle at high speed. For example lots of small files, like photos. Those are always slow on mechanical drives. Not much you can do about it.

4) What you think is slow is actually normal speed.

It is recommended to plug everything into a centered switch (prefered 1Gbps switch or faster)

#1 is possible. 2, 3, and 4 are unlikely. I cannot bypass the wifi because I'm not allowed to run ethernet from my room to the main router.

It is because the server and router are not Gigabit. I guess i'll add that to my wish list...
