download speed on additional downloads decreases

IE 6 ----

My main ISP is Comcast cable.

I notice that after downloading a couple of big files from a site, the
download rate speed on additional downloads decreases -- from cable speed to
dial-up speed! What gives?!

You don't include any numbers, but basically if you have two downloads
going, they have to share the pipe so max speeds are half for each, etc.,
for additional downloads.
Also IIRC with cable, you share the bandwidth with nrighbors on the same
line too so some of it depends on what is available for you to use from the
overall whole.

Hi Pop --

As a recent example: Initial download speeds were 350-500 Kb, but, after
several downloads, the speed dropped to 40-50 Kb.
There was not more than one download at a time.
There was no other PC active or powered up on the LAN.
There was only Comcast active as ISP -- the other is a dial-up I have for
backup, but obviously it was not dialed up.

After rebooting, I got the fast speed back again; however, after several
downloads, the speed again dropped!?!

Ah; is the situation almost always corrected with a reboot? You're right,
those are very substantial drops in speed. If the reboots always correct
it, then it sounds like something is neglecting to release something to
enable the speed to jump back up.

How many simultaneous downloads do you run? Several? Over 5? I think the
default limit is two, but I know it can be increased and sometimes that can
cause problems but I have no idea why.

Have you asked your ISP if they throttle your line if you do too many
downloads in too short a period of time? I know some do and Comcast may
well use throttles from other things I've heard. I left an ISP for that
very reason. Well, and because DSL became available.
Your ISP might be able to shed some light on it.

Pop,

Yes, in these cases it may be around 5 when the shift takes place. I didn't
realize ISP's might throttle your line if you do too many downloads in too
short a period of time. I'll have to check with Comcast.
