Ok great.  I think this will work.  Here are the two files you will need:

CNUDB.py is class ConceptNetDB with a test I added when the module is
run in Python
if __name__ == '__main__':
    c = ConceptNetDB()
    print '\n***** INITIALIZING ******'
    print '*************************\n'
    print "-- test took",str(round(time2-time1,2)),'seconds. --\n'
machine_All.txt is a file with 631 predicate lines
Next, here is a click event I executed composed in MS Visual C# 2005
Express on an Athlon64 2.19ghz 512mb RAM laptop...
        private void button4_Click(object sender, EventArgs e)
            PythonEngine ipEngine1 = new PythonEngine();
            ipEngine1.Execute("import sys");
            ipEngine1.Execute("import CNUDB");
            DateTime time1 = new DateTime();
            DateTime time2 = new DateTime();
            time1 = DateTime.Now;
            time2 = DateTime.Now;

**** Results from MS Visual C# 2005 Express ****
ran 5 times = {.250, .078, .093, .109, .078} seconds
sum = .608

**** Results from IDLE 1.1.2
ran 5 times = {.03, .03, .03, .05, .03} seconds
sum = .008

**** Results from Wing IDE 2.1
ran 5 times = {.05, .05, .05, .05, .05} seconds
sum = .025

I am not sure how to run it in IronPythonConsole.exe

And a side note, if you can this example creates some interesting
objects like c.bw_edges and c.fw_edges.  I believe at one time I was
able to .GetVariable c.fw_edges into a System.Object or maybe I
couldn't because of how dynamic these objects become. For example, if
I am interpreting correctly c.bw_edges become dictionaries; the have
Keys with Lists as values.
