Description

I've heard reports that the spergel profiles are much slower than galsim.

To Do:

  • profile to find optimizations
  • add benchmark comparison to galsim
  • implement those optimizations

Research direction

Start by profiling the implementation of the spergel profiles and comparing its benchmark results with GalSim. Review which optimizations are already marked complete, then identify any remaining bottlenecks and confirm that the profile performance has improved against the GalSim comparison.
