N36L Microserver through tp link AV600 powerline adapters
« on: May 29, 2014, 10:28:28 pm »
Thought i'd just provide some feedback on my server and setup that works really well with Mede8er 600 using tp link AV600 powerline adapters.

N36L HP Microserver - (yep there are newer better models) headless, WD 3TB red, 8gb, bluray drive, built in nic.
Ubuntu server 12.04 with webmin web interface, ssh, samba, nfs, ftp, madsonic server etc etc etc

Heres some comparisons using powerline adapters and through cat5e from server to laptop via a router using iperf/jperf
 - reading as follows which is better than expected.

first results are server to laptop via router

bin/iperf.exe -c xxx -P 1 -i 1 -p 5001 -f m -t 10

The depressing bit is when i run this setup through a pair of TP LINK AV600 power line adapters (with gigabit connections) from upstairs to downstairs.

This is what i get through the powerline adapters. (ignore the tplink software its massively optimistic and tells me its running at 250 mbps) its not. Clearly this is running gigabit though as i only get about 11 MBytes/s on 10/100 connections.

NOT SO GOOD - this is the reality of powerline adapters for me at least.
The good news is that this is enough to stream makemkv bluray ripped via commandline in the server and shared using NFS without issue.. I have had some stuttering occur using SAMBA, just save yourself the hassle and use NFS.
On the mede8er with NFS i find that setting tcp and auto works best and detects a higher than 32k server setting (whether this makes much difference im not sure)

Anyway i hope this gives people an idea of what they might achieve with a setup like this and if it will work with mede8er, which it does very well.
