that I am doing anything wrong.
Is it possible that FreeBSD is deferring flushing the dirty data, and then
forgets to do it when the same starting address is used etc?

In addition, I continue to look at the tbench numbers to see what the
story is with respect to FreeBSD and TCP performance. Perhaps I have
done something wrong.

seems possible to get using the SMB protocol on a 100Mb/s link.

Hi,
I am playing with a driver for the Broadcom 5700/5701.
It recognizes the 5700 in my 3Com cards OK, but seems to screw up the
TCP checksum.
Switching off hardware checksum capability fixes it.
Does anyone know the details of which stepping this stuff worked on?

OK, that makes sense, because I wasn't getting past first base. SYN ACK

The driver I modified is actually for the 5701, which works fine with
all checksum offloading enabled.
I will try to disable just
suggestions or any big objections?

It seems that each of these reduces the performance penalty that processes
that might be sharing the file, but which have not locked the file, might
have to pay.
Option 2 looks easy.

Which still means that the correct functionality is implemented, but we

Hi folks,
I am running into a problem with AIO in Samba 3.6.x under FreeBSD 8.0
and I want to check if the assumptions made by the original coder are
correct.
Essentially, the code queues a number of AIO requests (up to 100) and
specifies an RT signal to be sent upon completion with siginfo_t.
