With reference of your simulation purpose, to reduce sim time you can:
1- select an appropriate Solar Distribution algorithm in Building obj: leaving off "Reflections" increase speed time , as well to move from FullInterioAndExterior to FullExterior to MinimalShadowing. Generally FullExterior is a good compromise (at least as a starting point ) between acccuracy and sim time
2- use window multiplier rather than model each wondow with a fenestration obj
Blinds control on W/sqm hitting windows allows upspeeding solutions I stated. This could be different if you need a detailed interior solar distribution : e.g.
-to have daylighting illuminance maps, or
-for artificial lights dimming based on daylight illuminance level, or
-to model indirect solar daylight from a zone to an inner one through an internal window,
-etc

2- use window multiplier rather than model each window with a fenestration obj
Blinds control on W/sqm hitting windows allows is compatible with the upspeeding solutions I stated.
