Millions of previews #175

Open SimplyCorbett opened 4 years ago

SimplyCorbett commented 4 years ago

I need to generate a couple million preview images.

Is there a way to speed this up other then what's listed in #107 ?

Is there a way to run multiple previewgenerator processes at the same time in parallel?

I have the optimizations of 60 jpeg quality set, etc. But it's still a very slow process - and infact, it generates faster by just browsing the gallery on nextcloud.

Interestingly, viewing the files via file manager with webdav is significantly faster at (local) preview generation.

The PR https://github.com/nextcloud/previewgenerator/pull/385 could help with this.
