Which one is the server? Windows or FBSD?

I have no problems with either one being the server. The problem is
when FBSD is the client.

I wrote a daemon that executes operations on old DBF/NTX (clipper)
files (Yeah, I know ... but that's what they have for 20+ years ..).

Anyway, a site interacts with this daemon via tcp, with commands to
add/delete/update records/indexes, as well as finding keys on the
indexxes.

I prepared a test that has several of these routines together on a
10.2-STABLE machine.

Enough to say that when executing the tests with the files stored
locally, the whole test takes 3-4 seconds to complete.

When doing the same test with the files on a share on the same wire (1G
connection, no matter which OS runs the share), the test takes around
3:50 minutes to complete!

I am preparing a Centos VM and compiling the deamon on it to check the
results.
