все още никой не ми е отговорил на въпроса[X]RAVEN написа:При слагането на SP2 върху WinXP SP1 чрез ъпдейт (изобщо има ли такава възможност и ако има..) затрива ли се регистрито за софтуера който имаш до тук и другите там бози или всичко си остава както преди?

За съжаление е на английски но ето:
Hey guys, i just wanted to point something out. SP2's TCPIP.SYS limits the maximum half-open connections made PER SECOND. So yes, you can have 400 connections open in EMule, and yes BT programs let you have 100 or more connections per torrent or 1000 globally by default. That's the number of concurrent (total) connections you can have and that is the number that is controlled by the registry key on the first page of the post. These numbers are not related in any way.
A half-open connection means a connection that is open on your end but doesn't nessessarily have to be connected by another peer, so like opening a listening port that has nothing coming in yet, or requesting a connection to another machine but not established yet. Anyways, you get 10 of these per second under SP2. That's admittedly pretty low for BT or any p2p sharing prog where you can connect to say 200 people within a couple seconds time. But, what happens when you manage to hit this limit for whatever reason is the TCP/IP stack goes into a flood control kind of mode, and queues pending connections and processes them at the rate set by Max Connects per Second (ie. 10, or 50 if you've patched).
Now, if you consider that for a second (or 10 connections), it's pretty rare that any application you're running needs to establish a huge amount of connections for any considerable length of time. Usually it's a burst of connection activity - when you start a torrent or download a whatever you crazy eMule people call it - and once they're established there's a pretty big dropoff. So, basically the only way this setting is even affecting you is it takes a few more seconds than usual to establish connections when there's a lot of TCP/IP activity.
That's it.
In fact, in Azureus there's a feature, "Slowly connect new peers", and it does the exact same thing as this TCP/IP stack change does, altho i'm not sure of the rate. This isn't unique to Azureus, it's a concept that's been around for a long time - look at mIRC flood control, it's the same thing. The point is, because mass-opening connections is an effective way to make an OS scream like a little girl, many programs that have the ability to do so already have built-in traffic control you've just never noticed.
Seriously, the only thing that will be hindered by this change is software that opens a very large amount of new connections in a very short amount of time, for a very long amount of time. i think that made sense. you get what i mean. other than port scanners and malware/worms, i can't think of anything else that would require more than 10 (or 50) connections per second for any reasonably large period of time. (there very well may be legit programs that do, i just can't think of any).
Sorry bout the long post. One of my biggest annoyances is misinformation. Thanks for your time and please try to spread the word.
