Here is an example from sysstat when I am simulating the slowdown condition with 4 CIFS clients on gigabit fetching the same file.
Are the nfs and cifs clients on the same 1 Gbit link?
I see that you are pushing over 100 MB/s over the network and if that is only 1 link then that seems to me to be reason for the slow response times. My advice would be to put the nfs and cifs traffic on different 1 Gbit links.
