Hello Alex,
i have recently ran into same problem with wkhtmltopdf,
on my fairly complex view it timed out, while on simple (i.e CRUD
views) it worked fine.
I assume you are using pdfkit gem's middleware to simply generate the
files.

If that is the case, turn the middleware off and configure your pdf
print in respond_to block in your controller's action
This worked for me, now even the complex view generates as quickly as
the simple views and i have complete control over which action gets a
pdf view

Hope it helps,
Filip
