download speed from NY to LA
I am a testing a server in New York datacenter and I tried to download a (135 Mb) file from a server in Los Angeles.
From New York I am getting at 451.99KB/s and takes me about 14 minutes to download the file. From a server in different datacenter in Los Angles I get about 6657.31KB/s and takes me about 22 seconds to download the file.
I was just curious if the speed I'm getting from New York to Los Angeles is good? Or is my download rate slow?

Hello,
I tried the speedtest from Washington and got a 70Mb/sec download 40Mb/sec upload on a server in LA. If I try a server in NY I get about 104Mb/sec and 64Mb/sec upload.
I think there is some confusion. I am trying to download a file from Los Angles. From another server in LA (different datacener) I could download the file in about 22 secs. If I try to download the file from NY it takes me about 6 minutes. I am not trying to download a file from two different servers in the same location.

yea i understand that you are not trying to download at the same time.
Is this what your doing?
1) NY machine1 -> LA Server 1 = 22 sec
2) NY machine1 -> LA Server 2 (different datacenter) = 14-22 minutes
If yes, my point is just because both servers are in same general location (LA area) you cant expect similar download speeds. Each datacenter has their own bandwidth and traffic situations that will affect your download speed.
You may want to run a traceroute on each download to see if there are different paths.

If the paths are similar, then the problem is the LA server on download#2 above

Hello,
This is how I'm downloading
1) NY Machine -> LA server 1 = 6 minutes
2) LA server 2 (diff datacenter) -> LA server 1= 22 seconds
The file is 135 Mb. Is 6 minutes download a good speed? Traceroute from both paths are decent (about 80 ms between NY and LA).

Thanks for your help Mez4343 I will look into this and let you know, I also been looking at http://www.ipbalance.com/traffic-analysis/throughput/104-tcp-throughput-calculation-formula.html for tcp throughput.
Bottom line is you can only verify 1 access point to another. The idea that 2 servers existing in the same sort of location should have the same download speed is not guaranteed.
To verify your NY download speed to LA indepenently, I would run a Speedtest. I use http://www.dslreports.com/speedtest?java=1 and they have a LA server for you to test.
