Kimsufi network speed difference between datacenters ?

Hi,
I was lucky to get a Kimsufi 4-C from last flash sale. I got a i5-2400 in RBX-4.
I also have a Kimsufi 3-B from a previous sale: this is a I5-760 in RBX-1.
I noticed my new server has consistently much slower network speeds than my other server.
Does anyone have a possible explanation or have the same experience ?
Thanks !
Speeds from RBX-4:
Location Provider Speed
CDN Cachefly 10.9MB/s
Atlanta, GA, US Coloat 468KB/s
Dallas, TX, US Softlayer 2.05MB/s
Seattle, WA, US Softlayer 1.73MB/s
San Jose, CA, US Softlayer 1.47MB/s
Washington, DC, US Softlayer 2.51MB/s
Tokyo, Japan Linode 1.27MB/s
Singapore Softlayer 1.35MB/s
Rotterdam, Netherlands id3.net 3.03MB/s
Haarlem, Netherlands Leaseweb 5.80MB/s
Speeds from RBX-1:

They even are diffrent between racks in the same DC, unless you get some huge package loss, this seems fine.
Welcome to the neighbourhood I guess
Agreed, these speeds are not alarming, but still around 30% of the speeds on my 3-B server ?
This what I though initially as well, but then the CDN Cachefly would suffer as well, no ? And it seems CDN Cachefly has around 100Mbps connectivity ...

Yes 100Mb/s, not 100MB/s
You just got one of their "bad network" servers. There's no correlation to what causes the problem, some report being in the neighbor racks or same rack with the speed difference like your two. See this for example: https://www.lowendtalk.com/discussion/comment/2110362/#Comment_2110362
You can try filing a ticket, after tons of back and forth, with them asking you to retest again and again, asking root password from your server, then telling you "everything is fine", if you're extremely lucky, they will do "something" (my guess is, fix a configuration error on a switch), and it gets instantly fixed. This has been the experience of people with the same problem, unfortunately it's scattered across the "sales" threads, such as this one: https://www.lowendtalk.com/discussion/106785/kimsufi-ks-3c-is-in-stock-again/p1 RBX4 is mentioned multiple times there as well.
They have been throttling mine dedicated lines for years. 100mbps my ass, it never exceeds like 8mbps.
