Ofp saturating upstream bandwidth

[Kuja- 0]

For the past 6-8 months I've been getting inexplicable lag in OFP, with extremely low bandwidth and pings completely disproportionate to my connection (512/128 ADSL), server capabilities and distance to the server.

I serendipitously discovered the problem today - OFP is trying to send between 8-12kB/s constantly, no matter what I am doing in game, and it is saturating my upstream bandwidth, which fubars the entire connection, causing the aforementioned problems.

When I limit OFP to 8kB/s up, the problems are instantly resolved, however it causes desync during periods of intense action, so it's not an optimal solution.

Noone else from the server I play on suffers these problems, and the admin (lt damage) said upstream should typically be between 3-5kB/s. Can anyone explain why this is happening, or know of a way to stop OFP sending so much data, without having to resort to capping the process to 8kb/s?

How did you even cap it in the first place?! I didn't know you could do stuff like that.

I can not begin to imagine why the client is sending so much data, it should not need to, I think this is something only Suma can speculate on.

If it is constant 12kb/s and after connection, and happens even after complete OS reinstall and OFP reinstall, it MUST be hardware related.

If it is it must be how OFP network packets are treated by your adsl router. Maybe if the frames being sent are too big they are being dropped and ofp is sending 3x as many packets to compensate, hense no bandwidth and constant use of upstream. If this is the case it sounds like MTU configuration for the hardware.

What is your MTU set to for your modem? Have you tried adjusting it? Have you tried resetting your modem to the factory defaults and seeing if this effects your upstream use?

What the hell is OFP doing with 12kb/s of data from one client.. makes no sense

Well, unless it is that clients group doing something. Pressing several movement keys also adds a constant transfer load from client.

I have seen his problems, and you've seen it described above.

We can rule out:

Holding a button on the keyboard down or pressing a lot

Group in which is player is in seeing a lot of action, (it's a constant problem, his ADSL Is choking from compensating for so many upload packets) it is not a mission thing.

It is software independent, I am almost positive its hardware related, process of elimination my dear Watson.

Spyware?

He has this problem immediately after a complete format and OS reinstall, unless spyware was being installed along with his OS updates

Spyware?

Yeah, I was going to say this as well. Also consider closing any chat programs especially ICQ and/or IRC.

Edit: I reccomend EndItAll 2 to close all programs you dont need before playing. http://home.ptd.net/~don5408/toolbox/enditall/

Do you use a virus checker/firewall? In between reinstalling XP and going to windows.update i am infected usually by some worm or other crap in 1-2 mins....Make sure u have all of the latest definitions for virus programs...

I had a problem with windows media player.

I had 6gb of data stored in its media library, and at least once a day it would search for updates, this would make my normal ping of 19ms to a uk server rise to 200+ with little to no bandwith and huge amounts of desync. If you got huge amounts of media data in your media player library you could have same problem.

Sorry, I forgot about this thread

When I first started getting the problem, I assumed it was a faulty router.  As part of investigating that, I tried MTUs (and the corresponding MSS) from between 1400 -> 1500 (PPPoA VC-Mux).  I also tried running it in 1483 bridged, half-bridged and using the inbuilt PPPoA client.  At the moment I'm using 1500 and a few network monitoring tools indicate that all UDP datagrams are being received successfully and there is no packetloss when pinging the server with a 1472 byte packet.  In addition, AFAIK UDP does not use ACK packets, so if the MTU was causing packetloss, my client would not be aware and hence attempt to resend.

I use ZA Pro 4, although I've tried disabling ZA Pro to no effect, and I've also tried using the inbuilt firewall on the modem/router.  I don't use any AV or adware progs, but I am 100% certain that I have no viruses, trojans or spyware.  Utilisation is zero unless I am purposefully doing something.

I've tried disabling all but the most necessary windows services before running the game, elevating the thread to a higher priority, testing literally 5 mins into a fresh install and so on.  It is interesting to note that OFPs upstream usage drops from 10-12kb/s to the normal range when I alt-tab out of the game, which in means that by the time I have alt-tabbed back in, high pings and desync have disappeared temporarily.

WMP is disabled from accessing the internet and I've never created a media library within it.

There are various programs that allow you to limit the up/downstream bandwidth of individual processes, on a per adaptor basis.
