[Samba] Curious Question about Multiple CIFSD's

I know this isn't the right place to ask this question, but does anybody
know if it's possible to force a Linux client machine to spawn multiple
cifsd's when connecting to a SINGLE Samba Server? I seem to be running
into some Linux cifs client limits with a single connection. One cifs
client can talk to multiple Samba servers at around 100 MB/sec
(aggregate) over a single GigE connection. But the client stumbles
trying to do more than around 40-45 MB/sec to/from a single Samba Server.
If I connect some "shares" from "Samba Server A" via CIFS and other
shares via NFS, I can get about double the aggregate throughput that I
get if I connect all by CIFS. So, the bandwidth between the two machines
has the potential to be much higher than what I get just by CIFS. And of
course FTP and RSYNC without encryption shows almost line speed.
I am experimenting with some of the CIFS tunables (cifs_max_pending and
CIFSMaxBufSize). For various reasons, I have to mount with "directio"
so wsize and rsize aren't really relevant.
But it seems the easy way out might be to somehow get multiple cifsd
processes talking to the same server. Is it possible? What if I give
more than one IP Address to the SAMBA Server? Can I connect some shares
to one IP address and other shares to the other IP Address? Will that
result in more than one cifsd?
