Increase preview rendering speed

[iosory7]

Preview rendering is almost 3times slower than the v2.9.8.
Is there any way to increate rendering speed with v3.x.x ?

• CTRL + SHIFT + P -> AsciiDoc: Open Preview
• It takes 85sec to render preview with some adoc + v3.2.0, but only 33sec with v2.9.8

Environment

• Windows10 22H2
• AsciiDoc extension version: v3.2.0 vs v2.9.8(w/ external asciidoctor.js)
• VSCode version: 1.87.0
• Electron: 27.3.2
• Node.js: 18.17.1

Even 33 seconds seems unreasonably slow. You will need to provide a reproduction case otherwise I won't be able to help.

I created a adoc set (the content is meaningless) to reproduce the symptom.
Please find the attached.
I found that update preview took more time than new preview...

v2.9.8

• new preview: ~ 5sec (constant)
• update preview: ~ 5sec (constant)
  v3.2.0
• new preview: 8~12sec (variable)
• update preview: 14~40sec (variable)

Thanks.
