As explained in other occasions, the download speed has nothing to do with the installer and has nothing to do with our server. Normally, you are always supposed to download very quickly, because you never connect to our server, you connect to your local cloudflare node.
Except in one case: if you are the first one accessing that node that is requesting that file (a new file or a file that has been updated). In that case, your node will forward the request to our server to get its own copy, and from that moment on (until the file changes again), everybody in your area will download very fast from cloudflare, which is very fast.
So, the only time you are affected by our server speed, if when you are the first one asking for a file. And yes, we updated our server with a brand new system, way more powerful and with more memory, using an ISP that is giving us better upload bandwidth, which should improve BOTH the "first guy downloading" time but also the time it would take to replicate all 270+ cloudflare nodes around the world, so you should have seen some improvement. 99% of the times ( 99.98% of the time to be precise ) you'll download from cloudflare, which caches 99.98% of our total transfers, according to their stat.
Now, about the issue of downloading single files: my local cloudflare node is FRA (Germany), and I made the following test: I removed the two Mototok folders and performed a Live Update: it took exactly 3 minutes and 10 seconds from start to finish, I couldn't check the speed, because missing models and textures were downloaded very fast, most of the time was spent doing other things and checking which local files are present rather than downloading.
So, if you noticed a very slow download for the individual files (assuming we were on the same node, there are several in Germany), perhaps there might be something else, like antivirus scanning every downloaded file and slowing down the process. Possibly an antivirus in the router too.
