My setup: mldonkey on a fast machine and the shared
files  stored on a slow NFS directory.
I'm using ltrace to see what the mldonkey is actually
doing.

I started the mldonkey 2 days ago and it started
processing of the 30 files (20G) of files I want to
share. Currently if i look at the contents of
shared_files.ini I see an entry for smallest shared
file (300M) 3 times and an entry for the second
smallest file (500M) once. The entries for the smallest
file appeared in about 12h intervals and the second
smallest quite soon after those.

The ltrace is showing how mldonkey does the md4summing:
it keeps looping over all the files in the share
directory. For each file it seeks to a (random?)
position, reads 10M and calculates the md4. And then
goes back to the loop and reading an another file.


Bug #1: It seems that the already processed files are
not removed from the list of files to keep processing.

Bug #2: Why are the files not read sequentially? Can
this be configured somehow?

Bug #3: While reading the 10M part of a file (which in
my setup takes 1,5 minutes the mldonkey does not
respond to any input or network packets making it
time-out many connections. Between the reads there is a
30s period where everything works smoothly before the
next read begins.
