Default Download speed slower than Upload Speed

Usenet is not an e-mail venue. Newsgroup posts should have a maximum
physical line length of 76 characters, or less (to permit indentation of
quoted content in replies). Configure your newsreader (Outlook Express)
to physically wrap lines (rather than to make each paragraph a really
long single line).

Following quoted content was wrapped to maintain a physical line length
of 72 characters.


Thanks.

(This is a new question about a different Verizon DSL line from my
previous posts about DSL vs cable.)

I'm working at another location now which has Verizon DSL. The speed
of uploading files via FTP is 200-400Kbps -- slower than it should
be, but fine for what we're doing here. However the download FTP
speed varies from 15-35Kbps, way too slow for most work. Verizon DSL
tech came out and checked -- the upload speed on the Verizon side of
the box was 500K, but the download speed checked out at 1.5M. This
location is 2-3 miles from the Verizon central office.


Uploading and downloading from *whose* FTP server? If someone else's
then maybe they have its bandwidth throttled how you experience.
Perhaps there are only a few uploaders so that bandwidth load to the FTP
server is low but it has lots of downloaders so that bandwidth has to be
shared amongst all those users.

My question is - why is the download speed fast and upload slow?
Could this be due to something on my end? modem, OS, internal
building wiring? OS is Win2000.


(Now the transfer speeds reversed. Corrected in your reply.)

No matter what are your speeds, you cannot exceed what the file server
wants to dole out to you. So you'll need to check with whomever
administers the FTP server as to why your download speed from them
(which is their upload speed to you) is so slow. Your download speed
will be affected by their maximum upload speed along with what chunk of
their upload bandwidth they portion to your connection along with all
other concurrent connections to them. What is their upload speed? How
many concurrent connections do they allow (i.e., sharing of bandwidth
amongst how many users)? Did they configure their server to have slow
outbound speed (upload to them, download to you)?

Have you tried downloading a file from the FTP software with all your
security software disabled (anti-virus, firewall, HIPS, whatever)?

Besides what the Verizon tech measured, what do you get when you visit
speedtest.net and see not only what is Verizon's speeds for you on their
network but also what speeds you get when connecting outside their
network?


Speedtest results are exactly the same as those displayed when sending/receiving flies via FTP. And, yes, I have sent to various different companies' servers and all results are the same. Download speeds are 10 times slower than upload with all, including speedtest.
