The compiler that is in the Lahey/Fujitsu Linux Express package and the one
that is in the Fujitsu package are the same. The products differ in command
line syntax for the more obscure switches (they have different drivers),
documentation, bundled tools, price, support terms, packaging, etc.
I believe that Polyhedron is planning to publish benchmark results for Intel
Linux compilers. I'm surprised to hear that you are getting slower results
on Linux. We have not run extensive benchmarks yet versus our Windows
products, but we've had nothing but good reports on performance in our beta
testing. Can you send me your results, your machine configuration, and the
switch settings you used?
