Guys,

I have been investigating a problem for a mate here. He was complaining of really slow P2P startup. This is what I have found out, it may help someone, and it concerns users that have XP and have installed SP2

It affects all P2P applications, but particularly 'emule'. The reason for the decline in performance is a security feature that Microsoft introduced with SP2. In order to limit the rapid spread of worms, Microsoft limited the number of half-open connections that were allowed.

Half-open connections occur where your PC tries to connect to another PC. Until that PC responds to complete the connection, or the request times out, the connection is considered 'half open'.

With Windows XP SP2, the maximum number of half-open connections at one time is 10, and this value is hard coded in TCPIP.SYS

There is a patch available to over come this, but it is not supported by Microsoft. If anyone wants these details, then PM me, as I wont post it here.

Good info but I get a LowID whatever I do with emule..

I think its due to the ISP throttling (changed ports so how can they know that ??).. Tried all kinds of router configs and port settings.. ALWAYS a LowID..

Never used emule but I've just started using bitcomet and it's great.

Don't know if this is any help but here's a list of common p2p ports that ISPs throttle that I found on another board....

The blocked ports list include, but is not neccessarily limited to, the following:

Direct Connect 411 - 413
Kazaa 1214
eDonkey 4662
Gnutella 6346 - 6347
BitTorrent 6881 - 6889
