Slow Network Speeds Help!!!

post #1 of 16
Thread Starter 
Dose anyone know of a program to check network speed that is freeware and not bloated with spyware?

I set my server up to team the 2 1Gb ports on the mother board and it seems slower than when I had it as 1 connection? even slower than when I was using my Intel Ethernet Converged Network Adapter X540-T1 card this is a 10Gb/1Gb card.

Any ideas?

Little program that writes a file whatever size you want to a network share and then reads from it giving you the speed of both. That is what I use at client sites.

Also, how are you teaming? Are you using Server 2012? Switch independent? LACP?

I am teaming using Server 2012 R2 setting and the setting in my Asus RT-AC88U router

Right, so that would be switch independent which means you get no speed boost transferring to your server. However, data outgoing from the server should be increased in speed. Also, head over to Small Net Builder and check out the wired performance. You will see that the total simultaneous throughput is only 1406 Mbps. You will never see 2Gbps+ on a consumer router typically. For that, get a real switch.

Sorry, saw that the router supports link aggregation. You may want to check to make sure the team is configured for switch dependent.

In testing network performance you want to rule out the disk. The utility mentioned above uses the disk to test... so that's a specific kind of test. Typically you would use a utility called iperf. The latest version iperf3 is the best network bandwidth testing tool currently available and it's free! iperf can show you memory to memory transfer speed. When talking about greater than gigabit speeds, typically disk is the bottleneck. Also, on your consumer grade router you should be able to hit at least gigabit speeds if you enable cut through forwarding (CTF).

Thanks for the answers everyone but I checked it using LAN Speed Test and the results are as follows. This is a average of 10 runs of the test.

Using Asus Z87 Motherboard 1 Gb Port I get up 150 and down 525
Using the X540-T1 Card the up is 238 and down is 658
Using the Teamed ports from the Z87 Motherboard is up 498 and down 658

considering this is from a raid 6 array using 7200 rpm drives with SSD Cade Caching on the Raid card I think is is about what I will get??? I have a X540-T2 I need to put into the server and try teaming this.

Does my results look correct to everyone as I think this is disc limitations??

If you are using RAID 6, then something is not right. Those results are in Mbps correct? Also, make sure to make the file size like at least a couple GB for the test.

Here is from my workstation to a VM with no link aggregation. Also the VM storage is fairly slow.

I am running the test from a work station are you running from work station or the server?

Test was run on my workstation. Even from 1 workstation to another, you should be getting way over 125Mbps over the network. That is pretty bad.
