Test #1:

I've had files in my queue for DAYS with zero sources, when I can do 
a search using jigle.com and see 80+ sources.  When I ask on message 
boards "could so-and-so please reshare file X" I get replies saying 
"I've got dozens of full sources, I don't know what you're talking 
about.  Is there something wrong with your client?  Is your firewall 
open?" etc.

Test #2:

Running 2.01, I just performed a open-ended search and found a file 
with 10 sources.  I immediately added it to my download list.  It's 
been sitting there for 10 minutes, and I don't have a single source.

I then kill mldonkey 2.01, fire up 2.00, and perform the same exact 
test.  Grab a file from an open search, 10 or so sources(9 in this 
case), and within 30 seconds I have(surprise!) about 10 sources.

Test #3:

I had two files I've been trying to get for days with 2.01.  Zero 
sources.  Client had been restarted at least once every 2 days.

I fire up 2.00 and added the exact same two files.  Both had sources 
within 30 seconds.  One has almost 100 sources, the other has about 
10.  Tada.  10 minutes later, I have 567 sources.  Another 10 minutes 
later, same number of sources AND it's now downloading.

Test #4:

Timed Mldonkey 2.01's time to find a new server.  Almost 5 minutes to 
find ONE server.

2.00?  About 15 seconds.  Another 15 seconds later, it has 3 more servers.

Both using the SAME server list- copied it from the 2.00 directory to 
the 2.01 directory.

The only files I've been able to download since switching to 2.01 are 
those which are INCREDIBLY well spread...ie, 1000+ sources.  I 
suspect those came from other non-2.01 mldonkey clients that happened 
to hit a server I was on, were looking for the same file, and sent me 
their sources.  I've used mldonkey for months and NEVER had this much 
trouble.

What else do I have to do to convince you there's a problem with 2.01, Sven?

Oh, and by the way- I'm extremely hesitant to believe servers which 
claim to have a perfectly even number of users, especially above 
10,000.  Don't you find it the least bit suspicious that the majority 
of servers mldonkey 2.01 seems to connect to have really nice, even, 
round numbers of users?

  It was my experience, before switching to 2.01, that most servers 
tend to have a very odd number of users on 'em(1821 for example, or 
maybe 425, etc.)  It wouldn't surprise me if the servers claiming 
50,000 users are faking their stats.  Hell, they may be fake servers 
-period-!

  The four servers(temporarily raised limit; 2.01 had its config 
raised to a max of 4 as well for testing) I'm connected to at the 
moment(with 2.00) claim to have 2559, 697, 537, and 7313 users.  Much 
more typical/reasonable numbers, in my experience.  I doubt numbers 
in the 50,000 range are even possible, or that there are enough 
active clients.

  I bet if you tallied up the claims, you'd have the most incredible 
number of users.  I'd bet people are cooking their server's stats. 
Completely fake servers wouldn't surprise me either.  Strikes me as a 
great way to get sources.  Collect the sources from clients, but not 
let any other users see them.  What better way to attract new users 
by claiming an incredible # of connected users?  No concrete 
evidence, but it certainly seems like a possibility, doesn't it?

  I don't know the exact reason, all I see are the symptoms of a lot 
of servers refusing to talk to mldonkey 2.01.

You can tell us all you want about all the servers you're able to 
connect to, show us your client stats until the sun goes down- the 
fact remains that a lot of people are suddenly having a lot of 
trouble with mldonkey, and I've just pretty well proved that the 
problem is specific to 2.01, seeing how a switch back to 2.00 
resulted in active downloads-within-a-half-hour, instead of 
zero-sources-for-days with 2.01.

The common theme in almost every case is the following:

-user can connect to some servers
-user sees lots of folks downloading from them
-user can't find any sources for files(none.  Nothing shows up in the 
source list.)
-all were using 2.00 with no problems.  Switched, now they can't find files.

I think anyone who doesn't switch back to 2.00 at the moment is 
crazy.  But then again, 2.00 is now gone from the website.

Luckily, the network we all know and love comes to the 
rescue(provided you're able to actually download...)  I can't 
guarantee any of these haven't been trojaned(run at your own risk!)
