Package: jigdo-file
Version: 0.7.3-3+b2
Severity: normal

Hello,

My ISP has a Debian mirror, and thus over my fiber Internet connexion I
have 100Mbps access to it.

However, jigdo is not really benefitting from it, because it does not
pipeline file downloading enough: filesPerFetch is only 10 by default,
and since most files are not that big, the TCP connexion does not have
enough to download to reach a big download rate.

For instance, downloading the netinst image takes about one minute to
download with the default parameter. Raising the filesPerFetch parameter
by hand in /usr/bin/jigdo-lite to 100 reduces the download time to about
35s. Raising it further does not improve the time. Even just raising to
30 reduces to a bit less than 40s. Perhaps the default value should be
increased too?  It'll still be useful to be able to tune it.

Samuel
