The number of nodes per seconds is the reason for everything.
Fritz6 was cheated.
Shredder5.32 was more than 10 times faster in nodes per second.
If you remember the fact that Shredder is knowe\n to be slower than Fritz in
nodes per second then it is clear that Fritz was slowed down by something like a
factor of 100.
You should not give Shredder more than 1 thread when you have only one processor
unless you want to get wrong results.
