When I put a reasonably sized file in to the program (~20MB) the sync speed is extremely slow. I measured about 9kbps. What kind of problems could cause this?

I don't think it has to do with incorrect firewall settings (i believe they are all set to not block ports 80, 9701, and 443). This is being done through a university's ISP so could they be blocking P2P transmissions?

Thanks for any help

Hello,

Download process speed depends on many aspects:your internet channel, internet provider server's load on current moment, Collanos server load, same aspects from other space member side.
Information exchange occurs faster if space members are in one local network - then it happens directly inside local network. If you use firewall, even if all space members are in one local network, download speed are lover, cause firewall is additional transfer point with internal handling mechanisms.
One of the possible optimizations that we can offer from our side, as Connections timeouts and Internet provider setting are not in our submission, is adjusting connection settings on Collanos instance. Please find detailed instructions on next link

Also you may be with your space members in different local sub-networks, in such case file exchange also occurs through internet channel, not directly.

I've noticed the syncing speed has been very slow recently. Large files are particularly cumbersome. Lots of small ones seem to work better.

Hello,

In the post which is above is described factors which influence on file sync speed .  As in all internet file transferring - big files divides into small parts which are sent to file recipient, so it is natural, that small files sync faster. Main thing is to stay online during file upload.
