Hmmm. That's weird...

What Spectre +turbo does differently from regular Spectre is that the device evaluations are run multi-threaded. This encompasses a little overhead, so normally this is switched on when there are at least 256 devices per thread. Also the devices have to require evaluation - in generally this concerns mainly semiconductor models (BSIM, PSP, etc.).
If you do not want to compromise accuracy, there is generally very little you can do in Spectre +turbo. You could try to run with errpreset=liberal, but that reduces accuracy a little - it might be acceptable for your design/simulation.
Another alternative is to consider Virtuoso APS which is a true parallel simulator from Cadence, or look to high performance simulators from other vendors such as AFS from BDA or FineSim from Magma, to name just a few.
