Half-open limit fix



What is half-open limit?
Windows XP SP2 and later versions have only limited 10 concurrent half-open outbound connections.
After 10, new connection attempts are put in a queue and forced to wait.
Thus, the speed of connection to other PCs is limited.
(Microsoft do this to slow the spread of virus and reduce DoS attack)


To simplify, it means when surf forums, you can only load up to 10 images at once.
If there's 20 images, you need to wait another 10 images to finish then only it load.
If torrent download, you can only receive connection up to 10 seeds.
If Garena, you play DotA already connecting to 9 players then anything like auto-update or download interrupt, surely it lag.

To solve this, simply change the value to 256.
256 is tweak for gaming and download.

Anonymous said...

ur connection how many mb?
imo 2048 too large.

imagine you 1 time connect to 2048 connection, either pc hang or router cant stand it and hang.

ofc if ur equipment is good then no problem at all.

Anonymous said...

but remember not higher better, tweak depened on your connection.

Anonymous said...

if your connection got 4mbps then 1000 is okay.

512kbps~

i open 2048...
won't hang and lag wor...

Anonymous said...

some of you got that high like 1024~2048 without knowing it is come from chinese software like qvod xunlei pps.

and you thought 1024~2048 big like that will make you download faster, in fact this is totally wrong.

it makes you UPLOAD more to 1024~2048 other members that using qvod, xunlei, pss.

host game need upload connection so you're most likely can never host game.

not "no lag" just "not yet".

Anonymous said...

mine is vista.. 250 max... more than that is infinite symbol.

this web is the best!

Anonymous said...

streamyx rm66 512kbps package right?

set to 256 is more than enough.

Anonymous said...

if you surf forums like utorrent(another big torrent downloader community), they only encourage you set to 100.
They don't recommend you set more than that.

(explanation)
You download a file from 100 seeds without a doubt is already reach your max connection.

Why some Chinese softwares recommend you need that much like 1024~2048?
They want you to upload your files to 1024~2048 other people that using same software with the reason "Download Faster".
This kinda sounds like cheat and no offense I myself a Chinese too.

Set to 256 is more than enough.
You will never need that much.

but at garena also can creat game do host too..

no lag wor....

maybe 256 can adi, just i set to 2048~

Anonymous said...

ya small got problem big no problem.

but if TOO big and u host dota + download torrent.
sure cannot play, because u upload to 2048 people.
also too big will allow hack dos atk u, if anyone hate u xD

overall, just dont default low as 10.
256 is enough and balance.
if 1024~2048 that large, just dont open p2p application lik xunlei pps qvod(they lik to transfer via background) when host game.

This is for TCP connections.
But Garena is using UDP.
So the program doesn't change improve anything in Garena.

Anonymous said...

半开连接数而已,用过迅雷应该知道。

很多电脑新手都不知道什么用处,太小不好(10),太大有隐藏危机(1024)。

OMG said...

@above

thanks for the feedback ^^, but actually those p2p application's built in tool and this software by half-open.com do exactly same thing.

just p2p application automatically set too big for you will causes potential problem.

Will this program make your computer more open to virus attack ?

AS they says they put 10 to slow the spread of virus~~

Anonymous said...

no,if your pc already infect by virus.
then it will spread to 10 ppl.

no worries
