ARMv6TEJ is an instructions set. That says nothing about the performance.
You could have very slow and very fast implementations of the same ISA.

ARM11 is a CPU design. That is actually what matters most in terms of
run-time performance (besides the clock frequency obviously), and thus in
benchmarks. You could have completely different benchmarking results with a
different implementation of the same ARMv6 instructions set.
