RE: Number of mbuf clusters (NMBCLUSTERS)
You can increase the maximum number of clusters in /usr/src/sys/sys/sysctl.h and recompile the kernel. But make sure that you have a stable kernel image ready, just in case you increase this value so much that your kernel doesn't boot ;) I guess the default value is around 9, while for 256MB mem, you can go upto maybe 1 clusters.

RE: giving priority to udp over tcp?
TCP traffic as such does not get any priority over UDP traffic, but the way in which the TCP messages are sent (Data Streaming) is different from the way UDP messages are sent (Datagram). In essense, UDP messages wait till there's enough space for the entire message before the message is added to the output queue. Whereas, if there isn't enough space for the entire message, a part of the message is sent and the rest buffered. So, it might appear to be getting higher priority for some applications.

I'm using FreeBSD 4.5 and have custom applications that send receive network packets over both tcp and udp sockets. For the sake of an example, assume that the udp traffic is always constant, but the tcp traffic density changes. During times of heavy tcp traffic density, will udp messages which have been sent to the out queue typically wait in the queue longer before being sent out? Does tcp traffic get some sort of priority? If so, is there a way I can de-prioritize tcp traffic and up the priority of the udp traffic to make certain all the queued udp messages get out as soon as possible...? sysctl variables? does it depend on the network card driver, or perhaps i'm imagining something that isn't there and the two traffic types are totally isolated! ;) Thanks! --Ben To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

Nope. buildworld != builkernel. But buildworld does link the libraries.

RE: Unable to compile the kernel
I added a system call to the FreeBSD-4.6 kernel and compiled the kernel, it compiled properly. Now, in my new kernel, if I try to make some changes in the system call (very minor changes) and recompile the kernel, it gives a compilation error and stops. Which error? No fixed error. I just core dumps at random places. It sounds weird, since it's only a compilation and not a runtime library, but it's been happening since last night. Essentially, I'm not able to make changes and re-compile from my kernel, but am able to do the same from the generic kernel. The only difference between my kernel and the generic kernel is an additional system call. Which system call? My own system call. It's an empty function right now. Did anyone else have such a problem? Any suggestions? Tips? Could you post more details? I suspect some dumb a** must have hardcoded the number of system calls somewhere in the kernel and that's what is giving the problem.
