What latency are you seeing when you ping a server in Romania or Russia?

Here is a little experiment for you network experts.

First, ping google.com and look at the latency of a server located here in the US. What is the latency?

Now, ping baidu.com and tell us the latency.

Baidu is one of the largest internet companies in the world that has exceptionally fast connections to their servers.

The thing is, their servers are located far away in China. This means, just as if you were trying to connect to a computer in Romania, you're going to have latency issues that will DRAMATICALLY reduce transfer rates even when both machines are on super fast connections with major bandwidth.

That's simplified down pretty well.

So, what latency are y'all seeing when pinging google vs baidu?

So, what you are seeing is nearly five times the latency when doing a simple ping.

What do you think the latency might jump up to when you are sending packets of actual data being transferred?

Well, first of all, do you understand that latency will increase when you are moving data instead of a simple ping?

Move 200 MB of data to that server and tell me what the latency is and what the rate is.

LOL, the speed test must be fake news. Keep the kool aid flowing!

lol. actually zerohedge is a few guys that used to be in the hedgefund business but got banned from the financial industry.. hence they are always posting the most negative financial-related news possible.

What is the calculation for max TCP throughput?

It's RCV buffer size divided by RTT

So, pick your RCV buffer size (of what you think is used on that server) and divide it out by the RTT you get from pinging that server in Romania and tell me what throughput you get.

See above, and tell me what throughput you get when using the latency you provided.

Keep in mind that that throughput will be based on perfect conditions and not take into account many factors that would slow down a transfer.

So, do the calculation and tell me the absolute best case scenario on the throughput with that 186 latency.

Locate a server in Romania, ping it, and tell me what the latency is. Please provide the IP so I can test it as well.
routers, usually--but same idea yes.

this wasnt directed to me but since Im good at the subject matter i figured Id try one:
static-5-2-128-132.rdsnet.ro. resolves to 5.2.128.132

--- 5.2.128.132 ping statistics ---
20 packets transmitted, 20 received, 0% packet loss, time 19021ms
rtt min/avg/max/mdev = 169.009/176.564/197.010/6.146 ms



I portscanned them too for giggles


Starting Nmap 6.40 ( http://nmap.org ) at 2017-07-12 01:30 EDT
Nmap scan report for static-5-2-128-132.rdsnet.ro (5.2.128.132)
Host is up (0.21s latency).
Not shown: 995 closed ports
PORT STATE SERVICE
21/tcp filtered ftp
23/tcp filtered telnet
80/tcp filtered http
139/tcp filtered netbios-ssn
443/tcp filtered https



telnet ?? really? have to laugh. I haven't seen that show up in any port scan for years.
