When will the new BCE driver in HEAD be incorporated into RELENG_6?

[Conrad Burger]

Hi

It looks like there is a "new"  version of the bce driver in HEAD.
When will it be incorporated into  Releng_6?

We are currently having some  performance problems with a java
application on our Dell 1950s.

And it looks like it has something  to do with the speed with which
network I/Os are  performed.

We have Dell 2850s running FreeBSD  5.4/i386 SMP. With Intel nics (em)
and they are performing quite well.

With 34000 tcp sockets open the  maximum time it takes to perform a
single network I/O is about 100ms.

The Dell 1950s running FreeBSD  6.2-Prerelease/i386 SMP with Broadcom
nics (bce), the same application and 34000  tcp connections open.

The maximum time it takes to  perform a single network I/O is about 7000ms.

Most of the packets the systems  send/receive are rather small.

We are not quite sure what could  cause this behavior.

If anyone has any ideas of what we  could do to decrease the time it
takes to perform network I/O it would be much  appreciated.

Regards
Conrad
