Description

Hello,

I'd like to embed fsps into a framework which requires that instances be brought up and down rapidly. In particular, I'd like to get

import fsps
pop = fsps.StellarPopulation()

down to ~1 second or so (currently, for me, this takes more like 10 seconds or even longer). What are the major bottlenecks here?

Research direction

Start by profiling the shown import fsps and fsps.StellarPopulation() startup path to identify the major bottlenecks. Trace the Python binding into the FSPS initialization it invokes. Done means documenting the bottleneck and reducing construction time to roughly one second with a repeatable timing check.
