TCP/IP Connections

rlaserra · 08-08-2008, 09:20 AM

I am running a windows XP Pro machine with Apache server. I've tweaked the system to allow 40 max connections. This is strictly a webserver that is used to host pictures so a thread opens for each specific picture, downloads it and goes to TIME_WAIT and I need to know how to tweak the registry or apache, to kill the TIME_WAIT because once it gets to 40 then the webserver halts.

Please I really would not like to hear by windows 2003 server because I do not have the money for that and I am sure there is a way! Thanks

I Dont think that TIME_WAIT is causing your server to Halt. All it Should do is after a session reaches the default time, start default close of that connection.When your system reaches it maximum open sessions, it will force the oldest session closed. PHP scripts have been known to cause this kind of behavier.
Read here http://httpd.apache.org/docs/1.3/misc/perf-tuning.html might help you.

Yes what i am looking for is how to change the default settings so it closes the connections quicker....

TIME_WAIT is controlled by the windows registry,
System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
Value Name: TcpTimedWaitDelay
Data Type: REG_DWORD (DWORD Value)
Value Data: 30-300 seconds (decimal)
This small programm might help you http://www.lvllord.de/download.php?u...tch223d-en.zip

ive already used and ran that program. I also turned off windows update so that it would not get over written. I have 50 max connections allowed. I dident have the value data of TcpTimedWaitDelay in decimal value I had it binary. So i changed it, lets see how this works out. I cant go any lower then 30 seconds?

rlaserra · 08-11-2008, 07:21 AM

30 does not seem to do it. Do you think I've hit a barrier that there is nothign I can to improve the performance of xp pro. A suggestion that I got was to install SP1 and do not make any update, there is not any limits with that version. Then you run into problems with SP1. I need to make it kill the connections almost immediatly after finishing transmitting the data. Any more suggestions would be wonderful! but thanks for your help neilf!

try changing KeepAlive from on to off. Try raising the max clients (both are towards top of httpd.conf )

rlaserra · 08-11-2008, 03:24 PM

ok i will play thanks for the help. I will post my results hopefully with sucess. If you come up with anything else let me know.

Just one thing, why don't you have at least SP2 for XP? If your hosting a website then you definetly need it up to date against security loopholes. No buts.

**johnwill** · 08-12-2008, 06:27 AM

I'm curious as to what problems you think you have with SP1, or for that matter, SP2 and SP3? I have SP3 on several machines here, I don't know of any problems because of the service packs.

rlaserra · 08-12-2008, 07:44 AM

lol, I have sp3 on it right now. The issue with sp2 and sp3 they set limitations on the TCP/IP connections so that people are forced to purchase the server edition. Sp1 so I am told does not have any limitations on that, I am thinking of downgrading and giving it a shot, but I heard it has issues.... going sp1 and staying was a suggestion as i stated above :P

**johnwill** · 08-12-2008, 06:13 PM

Actually, that's totally false. You can have a maximum of 10 client connections on XP-Pro at any service pack level from none through SP3. The limits are 5 for XP-Home across the same spectrum.

**lazareth1** · 08-12-2008, 07:55 PM

Ok that sorts that out! Can you move this to the web development/design section of the forum johnwill, so it can get the attention needed?
