Slow Sync Speeds - Ubuntu Server 12.04 To Windows 8.1


Recommended Posts

Hello everyone.


I'm struggling to get speeds from sync. Here is the setup and my results.



Ubuntu Server 12.04

(4) 250GB Samsung 850 Pro SSD's in Raid 0

32GB Ram

4Core/8Thread Haswell Processor.

Dedicated 2Gbps Network Link



Home PC:

Windows 8.1 64


4Core/8Thread Haswell Processor.

150MB/20MB Internet connection.


As you can see I'm not having a hardware problem to cause any slow downs.


I have tried a predefined host, as well as using the Relay/Tracker Server.

My server can definitely talk to my home PC no issues - Ports are good.


I can't for the life of my get more than 2-3MB/Sec Upload to my Home PC.

Also while it transfers it will climb to 2-3MB/Sec, then dip down to about 175K, and start to climb again.

This is constant through the entire upload.


I'm testing this using a single file - about 25GB in size (Not hundreds of little files)


What I have experience in the past on a different server (This is interesting)

Maybe this is a known issue I'm not aware of.

When I had Sync on an Un-Raided drive - I would get great speeds. (Single SSD)

But it seems on Raid 0 - my speeds tank.



With my Home connection - In theory I can download at 18.75MB/Sec - Which I get close to on segmented FTP transfers.



What else can I try - Any suggestions?
