34 | | Simulation relies on the [gamma:wiki GAMMA] package. When doing calculations with a spin of 8,9, or 10, your system may appear to slow down or even hang. At a spin count of 7, a single FID experiment takes GAMMA 0.4 seconds, but at spin 10 it takes 1 hour and 24 minutes (on a 2.66 GHz Intel machine). [gamma:GammaVsSpin Here is a list of GAMMA timing results for various spin sizes]. The "slow down" may be compounded if doing a large number of individual simulations for different timings, or spacial locations. Note: The time it takes to run these specific jobs is virtually identical in GAMMA - when compared to Simulation - as there is little overhead converting arrays to and from Python, as compared to the overall time of the calculations. |

| 34 | When doing calculations with a spin of 8,9, or 10, your system may appear to slow down or even hang. A likely explanation is that for larger spins it take a much longer time for the spectral calculations in the underlying [gamma:wiki GAMMA] package. For example, at a spin count of 7, a single FID experiment takes GAMMA 0.4 seconds, but at spin 10 it takes 1 hour and 24 minutes (on a 2.66 GHz Intel machine).
