Well, if your workload is CPU-bound, the issue here is not really Solaris vs.
Linux but rather CPU power. You should try to run a generic (non-Python) CPU
benchmark (*) on both systems, perhaps this 6-8 factor is expected. If only
Python shows such a performance difference, on the other hand, perhaps you can
give us more precisions on those systems.

Regards

Antoine.
