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.
