I commented on this in an older issue, but I'm going to open a new one for performance issues.

I've got 45 api endpoints and am running swagger-ui under Swashbuckle (.Net) latest version. It currently uses swagger 2.1.3.

Before I started messing around it was taking over 4 minutes to display the endpoints UI. I went in and set the highlightSizeThreshold to 1, and finally just commended out the highlight-7-3 lib altogether. I did get a speed increase of about 50%, but a 2 minute load time is still very unacceptable.

Are you aware of what is causing the severe performance problems, and have an ideas to solve it? This isn't a huge API yet, but it will become one and I'm concerned about any attempt to support swagger at this rate.

I confirmed the backend is serving the requests in under a second, and the schema is around 1MB.
