Increase preview rendering speed #852

Open iosory7 opened 8 months ago

iosory7 commented 8 months ago

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...

sample_adoc.zip

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.
