Regards, Ptitoliv ___ I made some quick check, there is some information available. Most of it seems to be pretty recent. I suggest joining freebsd-stable@ as there is some questions going on about it there. You can also google for information on: net.inet.tcp.inflight.enable There may be other things to look at and good reasons to have it enabled, or disabled. Take from chapter 11 of the handbook: = 11.13.2.2 TCP Bandwidth Delay Product The TCP Bandwidth Delay Product Limiting is similar to TCP/Vegas in NetBSD. It can be enabled by setting net.inet.tcp.inflight.enable sysctl variable to 1. The system will attempt to calculate the bandwidth delay product for each connection and limit the amount of data queued to the network to just the amount required to maintain optimum throughput. This feature is useful if you are serving data over modems, Gigabit Ethernet, or even high speed WAN links (or any other link with a high bandwidth delay product), especially if you are also using window scaling or have configured a large send window. If you enable this option, you should also be sure to set net.inet.tcp.inflight.debug to 0 (disable debugging), and for production use setting net.inet.tcp.inflight.min to at least 6144 may be beneficial. However, note that setting high minimums may effectively disable bandwidth limiting depending on the link. The limiting feature reduces the amount of data built up in intermediate route and switch packet queues as well as reduces the amount of data built up in the local host's interface queue. With fewer packets queued up, interactive connections, especially over slow modems, will also be able to operate with lower Round Trip Times. However, note that this feature only effects data transmission (uploading / server side). It has no effect on data reception (downloading). Adjusting net.inet.tcp.inflight.stab is not recommended. This parameter defaults to 20, representing 2 maximal packets added to the bandwidth delay product window calculation. The additional window is required to stabilize the algorithm and improve responsiveness to changing conditions, but it can also result in higher ping times over slow links (though still much lower than you would get without the inflight algorithm). In such cases, you may wish to try reducing this parameter to 15, 10, or 5; and may also have to reduce net.inet.tcp.inflight.min (for example, to 3500) to get the desired effect. Reducing these parameters should be done as a last resort only. Note: In 4.X and earlier releases of FreeBSD the inflight sysctl variables are directly under net.inet.tcp. Their names were (in alphabetic order): net.inet.tcp.inflight_debug, net.inet.tcp.inflight_enable, net.inet.tcp.inflight_max, net.inet.tcp.inflight_min, net.inet.tcp.inflight_stab.

RE: Bandwidth Problems with Freebsd 5.x
It has already been suggested but obviously you have ignored it so I'll say it again - get the hosting provider on the horn and have them lock the switch port to 100baseT-half duplex, you then do the same, then try the test, then have them lock to 10base t full, you do the same, try the test again, then have them lock to 10base t half, you do the same, and try again.

Your testing is way to general to make the blanket statement that something is wrong with FreeBSD.

Re: Bandwidth Problems with Freebsd 5.x
If you are testing it through your home this test is irrelevant as there is a lot that could cause it to slow down if you test it from the freebsd box to another freebsd box on the same switch i bet it would be faster then the shity debian box the internet is a weird place one momment its quick another its slow try doing atraceroute on your DSL as i guarantee it's a problem with your DSL or whatever the box is connected to not the BSD box itself.

The machines are pluged in a 100 Mbit/s with via rhine network cards. On this same LAN I have a Debian Sarge computer. When I try to transferts big files beetween the FreeBSD and the Debian, I see that I have an assymetric bandwith : From Debian to BSD : No problem. The bandwitdh is OK : About 8 MBytes/s which is normal for a LAN I guess. From BSD to Debian : The bandwidth is quite awful = Beetween 300 KBytes/s to 1Mbyte/s. Network have been changed and the problem is still the same. So I thought it was a network problem. Then I installed an other FreeBSD on a different computer and plugged it in a completely different network and the problem is still here. That's why I think there is a thing to configure on the BSD system but I don't know why. That's why I am looking here for someone who knows this problem and who will be able to help me. Thank you for your answers Best Regards, ptitoliv Are you doing GET from each machine, or comparing GET to PUT? Get has always been a lot faster then PUT. I tried GET and PUT from the two servers and the problem is still the same. Put a monitor on the LAN and look for weird sending patterns. The 4.x FTP servers will stop altogether if you set the window under 1500 bytes. I don't know if its the server app or the stack, but its probably the specific application, as HTTPD seems not to have such problems. The problem still exists with HTTP and SCP requests. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
