I dont think Warren Harrison was saying that Strand in itself was not
much slower than Fortran. The benchmarks shown by Argonne indicated that
where Strand was used to construct the optimal parallelizing harness for
an application the *slowdown* due to Strand was not noticeable when the
application itself was achieving pretty much linear *speedup* on multiple
processors.
Where an application only spends 1-5% of wall clock time in the Strand
layer you dont notice the performance hit of that layer.

Blatant Commercial hit follows ( hit space bar if you are sensitive)

Strand is being continuously improved. Native code compilation is a
project under current development. New compilation strategies are being
finetuned for release.
The product is now available on networks of Unix V rel 3,4 workstations
subject only to compilation and your funds.
