Hi Tom,
Apologies for the very late Response. Only saw this today. Should probably check my email notification setting in this portal. (There is a high latency joke in there somewhere).
Wish you could tell my ISP that. would love to have 200-Meg upload.
They literally sell the Package in the 1000/50 configuration.
For the most part it runs pretty smooth, but from time to time I do experience random slow downs as if the network is congested.
Though it was due to hardware acceleration that is not enabled on the bridge.
The ISP connection itself is (Fiber to the Basement) from there it goes to the ISP router (in bridge mode) via coax copper cable that in turn connects my Mikrotik.
Don't know if that makes a difference at all.

Are you having any strange issues/problems with your " asymmetrical 1G/50M link from Berlin " ?Hi Tom,
Thank you for providing this free test server.
Also tested for less than a minute on an asymmetrical 1G/50M link from Berlin, Germany.
Tx/Rx: 53.0 Mbps/955.7 Mbps
Kind regards,

If my math is correct , you have an upload speed that is 5 percent of your download speed.
( Would anybody correct me if I am wrong here please )
On typical/average network devices that are receiving/downloading a TCP data stream will often have a 3 to 10 percent upload ( ACKs ) data stream.
The TCP protocol is bi-directional traffic where the receiving computer is required to send ACK packets ( I received your last packet - now send me the next packet ).
In your case , with a " asymmetrical 1G/50M link from Berlin " , I can see the following environment breaking your network with strange errors and data loss.
Lets say you have 2 computers on your " asymmetrical 1G/50M link from Berlin " Internet connection and they are doing the following:
Computer # 1 is sending an email attachment ( sending a file ) and/or sending video in a video conference where this computer is sending at 25 meg.
-- at this point you you only have 25-Meg free to upload because you are currently sending 25-Meg ( 50 - 25 = 25 )
Computer # 2 is receiving a data stream of 750 meg. This computer might need to send TCP ACK packets at a rate of greater than 25 meg.
** At this point , your network wants to send ( bursts rates ) at greater than 50-Meg. Because you are capped at sending at less than 50-Meg, both computers may now be having problems because of packet drops/loss on sent TCP/UDP traffic ( including sending TCP ACK packets ). Sooo , your network starts to break and things start running slower than expected/needed.
IMO and with my 20+ years of network experience , I have learned to never limit customer upload traffic to less than 10-percent of their purchased download account speed. I have found that when using less than 10-percent , I begin to have some customer complaints of network problems. So these days , I use a standard ratio of 20-Percent.
In your case , if you were my customer with a 1-Gig download rate , I would limit you to a 200-Meg upload rate ( not 50-Meg ). This with a 20-Percent up/down ratio, I would lever have any complaints about things not working to/from your Internet connection to me.
If I were you , I would check to see if it is possible to increase your 50-Meg upload rate to at least 100-Meg ( or better 200-Meg upload rate ).

Please , anybody - if you have an opinion and/or experience with upload/download bandwidth ratios that is not as I am saying , please give us your thoughts and suggestions.
