Throughput improvement in Fedora


hi,

In my home network, I wanted to make multimedia streaming setup. I use Netgear R7000. I connected MACbook pro 'EI Captain' via wireless 5 GHz.

I connected Windows 7 machine via ethernet to R7000. From Windows7 to MACbook when I run Iperf, it shows throughput of 700Mbps.

I removed Windows7 machine and placed Linux(Fedora Core 19) in the same place. When I run Iperf, it shows throughput of 650 Mbps. Is there any way, I can speed up throughput using Linux with any register settings. Please help me in this regard.

Thanks in Advance.
--uv.

- What kind of connection (wired, Wifi) did the Fedora machine use during the test?
- What CPU and network card do the Fedora and Windows machine use?
- Where all machines in the same vlan when the test was done?
- Where there no other bandwidth-hogging machines running at the time of the test?
- Did you save Iperf stats for all machines?
- Did you stream the same type of content during each test run?
* 19 is a very outdated release: please consider installing a clean Fedora 23 first.

A difference of less than 10 for a single test on a WiFi connection is not significant in my opinion. Run the tests ten times at different times of the day and come back.

Let me add to unSpawn's list that there is an endless number of factors that influences wireless LAN, including things that you have absolutely no control over - your neighbour's fridge, your boyfriend warming up a cup of soup in the microwave oven, or Donald Trump on TV.

Agreed, the difference is completely insignificant. You'll see the speed swing around at least 25-50% just due to changes in the environment, a difference of 7% in iperf is meaningless.

Indeed there's many aspects to Wireless networking that can suddenly degrade performance (I forgot to add legacy non-N devices) but there's also the fact that without enumerating, analysing and potentially mitigating influencing factors where you can you learn absolutely nothing. So here you have a choice: either drop the question and let somebody else decide for you (on the basis of an explanation devoid of technical aspects), or not.
