If you are using ArcMap and the Add GTFS to a Network Dataset toolbox, you should upgrade to ArcGIS Pro and use the tools included with ArcGIS Pro (no download anymore).  Here is a tutorial: Create and use a network dataset with public transit data—ArcGIS Pro | Documentation 

ArcGIS Pro is more efficient and better for solving large problems.

If the problem is still too slow, please include more details in your question so we can help you.
