Hey All. I was wondering if someone could help me out with a problem i'm
working on. It's very weird to me and I can't find any reason why this may
be happening other than possible a Queuing issue. Please comment.
I've done some testing to show the response issues from spikinisse
to an auburn hills tftp/ftp box. When a 9 meg
file is copied from one of the 6509's in Spijkenisse using tftp we
see a speed of 4k/sec (9041904 bytes copied in 2251.956 secs (4016
bytes/sec)
However, when I ftp'd a 2meg file from a server in Spijkenisse to
the same server in Auburn Hills, I see a speed of 166k/sec (2024013 bytes
sent in 12
seconds (166.12 Kbytes/s) Seeing as in Spijkinisse it is
approximately 8pm and they have 4 E1's, there should not be an issue with
over-utilization.
It intrigue's me as to how a UDP based application (tftp) can have
such a ridiculously slow speed of 4k/sec and a TCP based application (ftp)
has an
average speed (considering 4 e1's) of 166k/sec.
Spikinisse has a group of E1's to the cloud and our site in Auburn
Hills has a full DS3 to the cloud.
Spik is in the Netherlands, and Auburn Hills is in the US. Any more
information I need to provide?
