Multiplayer map download speed too slow

[Cloner]

Still not solved in 11.13, i have 100/100 internet and upload a 30mb map over 3 minutes to a 100/10 mbit peer.

I know :-)

In fact I'm working on it now.

So I finaly managed to replicate the problem -- Our file transfer doesn't handle packet loss very well... With packet loss of 5% and transfer rate limited to 200KB/s we download at 15KB/s ... Fixing it should be really easy now, right? :D

Hopefully fixed for 0.11.16 :-)

i seem to be having this issue in 11.22 , map download steady around 30kB/s was fine 2 days ago.

Still not solved in 12.29.

Steed begin with 2 Mbit/s and going down, by 50% is ca. 100 kbit/s, and by end of download ca. 10-40 kbit/s.

EDIT: I only just noticed this was in resolved since Feb 2015 already, nonetheless there have been improvements in 0.12.31 so my answer still stands.

Recently resolved bugs are usually only resolved for the experimental release, which might become stable later.
I believe this issue was solved in 0.12.31.

Steps to update to experimental:
If you're using the steam client, go to the steam library > right click factorio > properties > betas > drop down menu > experimental. If the drop down menu doesn't work please restart steam and try again and it should work.
If you're using the standalone client go to the main menu > options > other > enable experimental updates. then go to main menu > about > check updates.

Note that the server (or host) and all other clients have to be on the same version, too.

The steam flavor only list NONE under the drop-down for Beta.
It seems like we need a beta access code?

Are you sure you opened the properties of factorio? There are 12 different betas right now, try restarting steam.

I'm having a similar problem where the map is even smaller than 20mb but the loading is completely inconsistent. Sometimes it loads without problems in a reasonable amount of time while other times is loads less than one kb a second, this makes the loading time over 24 hours which is an Earth day. I try internet applications like Google Chrome when this happens and it usually works perfectly fine so I don't think it's my internet connection. This is a massive annoyance because I don't have days to stare at a monitor in silent anger and load a map just to play it.

Obviously the upload speed of the host is a factor as well, but in my experience, the map download speed is severely diminished by packet loss. Never the less, MP is redone completely and this report is too old anyway, so lets wait for the big update and go from there.
