Dear FreeBSD list,

I’ve been a silent reader for many years and as a sys admin have benefitted as a list member.

While enjoying FreeBSD in my professional environments, I’ve noticed that I cannot get a FreeBSD NFS server to support NFS read/write sizes of 1048576.

Is this a kernel limitation or can I use a sysctl to increase it up past 131072?

I can't seem to find much on line with reference to this.

Thanks in advance for your replies.
