When I start any download, it never uses all the bandwidth available, which is
usually around 6-7K/second (I'm on a 56K modem, so I assume these are
megabytes). Instead, I get about 1-2K/second. And then, when I attempt to
download multiple files, the remaining files get about .5K per second, which
never increases even after earlier downloads finish!
Reproducible: Always
Steps to Reproduce:
1.Start download
2.Start second download
3.Wait for hours
Actual Results:
I waited for hours
Expected Results:
Used all the available bandwidth, and then shifted the available bandwidth to
each next download, after the previous download finished.
For me this is a major feature, as I download files all the time in my work.
Seems to WorkForMe using Mac/2002100603/9.2.2. Mozilla downloads at about 150 KB/sec
via FTP, the same rate I achieve with other software over my DSL connection.
Doug, please choose a test file to download, and record some data on elapsed time and rate
using Mozilla as well some other browser or file transfer software. Be sure to let us know what
your test URL is.

Summary: The download manager fails to properly allocate bandwidth: it doesn't allocate all the bandwidth, and it doesn't dynamically reallocate bandwidth among multiple downloads when one download finishes. → The download manager fails to properly allocate bandwidth: it doesn't allocate all the bandwidth, and it doesn't dynamically reallocate bandwidth among multiple downloads when one download finishes.

Works for me with the 10/23 Mac 9 build. When one download is finished, the next
download rate speeds up.

RESOLVED/wontfix: this is reported only on Mac OS 9.
If this is reported on Mac OS X please REOPEN.
To speak to the general concerns, I am not sure where Doug got the 5-6k/second
bandwith calculation, but there might be reasons the download manager download
speed does not reach that level. That would certainly be worth investigating.
As for the increase in speed as one connection completes, that should pretty
much happen automatically, because the two downloads would use two connections,
and your TCP stack would automatically intersperse the packets that contained
the two files. It is unlikely there would be a real, data moving problem here,
although the display of this information can sometimes be incorrect.
