Hmm, I was a bit fast to draw a line, there are some possibilities to
have faster than hash table lookup using different algorithms...

So, I ask network developers about testing environment for socket lookup
benchmarking. What would be the best test case to determine performance
of the lookup algo? Is it enough to replace algo and locking and create
say one million of connections and try to run trivial web server (that
is what I'm going to test if there will not be any better suggestion,
but I only have single-core athlon 64 with 1gb of ram as a test bed and 
two core duo machines as generators, probably I can use one of them as a
test machine too. They have gigabit adapters and aree connected over 
gigabit switch)?
