Which form is "source element vector"? Is it the linear form

  L = v*f*dx?

How is this computed by SyFi (tabulate_tensor)? It would be
interesting to compare with the FFC code.

I'm not sure what your timeframe is but maybe you should also include
timings for FErari-optimized FFC code (in which case you need to bug
me about activating the optimization again in FFC). We did a series of
benchmarks for comparing plain FFC code with FErari code a while back
and the local speedups were typically between a factor 1-4:
