My company just recently implemented a full DS3 from our office in New Jersey to the headquarters in China. Needless to say the RTT is about 250ms which to my understanding is typical for LFNs. Here is where I am puzzled,
If I FTP a 29MB file TO China, time start to end is about 2 minutes, which is "ok", but if I try to pull the same file from China, it takes more like 16 minutes.
I asked the provider to adjust the TCP window size on both routers plus suggested to Windows Engineers in China to make sure Windows 2000 box has latest patches to support TCP Window scaling,,
is there anything else I can investigate?
Thanks ahead of time!!!
