I'm trying to learn how to use Boost.Threads with this example:
http://pastebin.ca/1472832

On Ubuntu 8.04 with Boost 1.34 I'm compiling with a makefile like this:
t1: t1.o
        g++ t1.o /usr/lib/libboost_thread-mt.so -o t1
t1.o: t1.cpp
        g++ -I /usr/include/boost/ -c t1.cpp

However I get very similar execution times for the single-threaded
version and the one which creates two threads.

What am I doing wrong?

thanks,

Anders W
