Moving ISR to SRAM

We are using S12ZVMC128. We would like to move some of the ISRs to SRAM for faster execution. What is the easiest way to declare this to the compiler? How much performance improvement can we expect in code execution speed between SRAM and flash? We are running the core at 50Mhz/100Mhz speed. Would the execution speed be about 2x in SRAM compared to Flash?
