More like a bit over 2-hrs.....  I got it in 18-seconds.

But....but....but....  "5M" doesn't mean anything.  Unless its  grandkid of 
the 3M Corporation, maybe.  5M what?  Bits?  Bytes?  Ice cream cones?

Cable Modem........10-Mbps uplink and 768-kbps on the downlink.

"5M" what?  Bits or bytes?

Mine are 24-hrs a day, 7-days a week....with some variation in performance 
due to link and net conditions, but even during prime time, it beats the snot 
out of a T1.

Know how some people have all the luck?  Apparently you are an opposite.  :-)
Okay, here is an actual example for you to ponder and meditate upon:
=====================================================================
May 18, 1997  10:15am
RETR bigfile
150 Opening BINARY mode data connection for bigfile(13181628 bytes).
Received 13181628 bytes in 16.9 secs, (7.46 Mbps), transfer succeeded
226 Transfer complete.
=====================================================================
There you have it, straight from the logfile.  Read and weep.  Now for the 
short course in Telecom 101:
"MB" means mega-bytes whereas "Mb" means mega-bits.  Lots of difference 
there. That's why your "5M" didn't mean anything.  One must always be clear 
in stating thruputs and speeds in either bytes/sec (B/s) or bits/sec (b/s).
Now a byte is 8-bits, usually, except in telecoms where a start bit and a 
stop bit for each byte sent have to enter the equation.  That makes it 
10-bits per Byte for telecoms.
The size of a transferred file in bits or bytes, divided by the elapsed time 
of the transfer yields the average link speed or thruput.
Lastly, because of v.42 compression, it is important to note whether a 
transferred file is compressed or not.  If not, the v.42 feature of the modem 
will compress it "on the fly" if both ends have v.42.  But if a file is 
already compressed, like MSIE 3.02, then v.42 can't compress it any further.
There is a lot of difference (in telecoms) between a 1-MB text file and a 
1-MB ZIP file.  The v.42 engine will distort thruputs to favorably higher 
numbers. To see that difference, take a large text file and send it as *.TXT, 
measuring the times.  Then PKZIP it, and send the sucker again.  You'll 
see.......   :-)
Anyway...my cable modem service is utterly awesome...and I have my entire LAN 
connected to the system....24-hrs a day, 7-days a week.  :-)

Two of 'em are easy to access:
