Virtual Server In Cloud Soooo Slow

[PaulU]

Hi all,

 

As a bit of an experiment I set up a virtual ubuntu server (c/o Digital Ocean) to see how it would perform as an offsite peer. The answer turned out to be, well, pretty bad.

 

A folder that took dropbox one hour to sync, took over 8-hours.

 

Now, I am not much of a tech wiz, by far. I simply followed various guides on-line to both setup & secure the server; then to install & configure btsync. Could there me something that I did wrong that led to such woeful performance ? BTSync ran - it just ran real slow.

 

Thanks for any tips,

 

Paul

Paul,

 

Could there me something that I did wrong that led to such woeful performance ? BTSync ran - it just ran real slow.

And what did you do at all? I mean can you please  provide more details on your setup and network, and peers, Sync version, files that you sync. etc?

The speed depends also on the files accessibility (for example syncing a network share will be slower), on writing/reading to/from the disk, so check the fs integrity, (in)direct connection of peers, sync version being up-to-date, and many other factors that need to be investigated individually. The most widespread are mentioned here. 

If tips don;t help, please send full debug log from all or at least two peers affected to support for analysis

Indeed, there are many factors at play. For instance, the peering between you and DigitalOcean can also be bad (though probably the upload bandwidth of a residential connection is worse).

 

One thing you could start with is copying a large file to the server using OpenSSH's scp. This is kind of a good baseline, since it is just a raw file transfer, but uses encryption too.

 

Also check that the transfers are not going through a relay. (There is an icon in the BTSync interface which is a relay indicator.)

 

Just as a reference: I have a cloud peer (Vultr), and syncing pretty much gives the speed I'd expect with our upstream (5 MBit/s).
