I have not found single threaded performance numbers to relate to overall application performance either.  That being said, I am aware of many installation using the Charon emulators that perform at or exceed "real" hardware levels.  A lot depends upon the application.  Some emulators perform JIT, others prescan the code stream and generate the instructions in parallel to their execution.  Your mileage may vary.

Dan is right. For these types of questions, the only meaningful answer is
the one obtained from the OP performing their own benchmarks.

Dan, do the emulator vendors support trial licences so the OP can perform
these tests before committing to purchase the product ?

If so, I would recommend to the OP that this is the path they go down.

Do you ever get user applications that have race conditions on your
emulators that were never exposed on their original, slower, hardware ?

No reason for asking. Just curious.

Simon.
