In all those cases when our eink reader is slow at opening or displaying pdf files we can use k2pdfopt app.

Pdf rendering can be slow because of complex pdf compression method involved, because of big pdf page size, because our reader is slow at zooming in landscape mode etc.
In the case of complex compression we should just use bitmap mode in k2pdfopt, resulting with bigger pdf than original e.g. 50 MB instead of original 5 MB, which will nevertheless be simple for majority of eink readers to display quickly.
In the case of very big pdf page sizes we should choose our reader's exact screen size and resolution so that k2pdfopt can adjust pdf accordingly.
For reading in landscape mode we should use k2pdfopt's landscape mode that will automatically crop the margins and cut out the page into a two or three, for the exact landscape screen size and resolution of our reader.
If we have Adobe Acrobat we can choose its clearscan mode or just print pdf out for the exact dimension of our reader or by using its tile mode(poster mode in Acrobat Reader) if we want to read it in landscape mode (e.g. three screens per pdf page).

Like with Kindle DX, though, the best solution for your InkPad is to install KOReader thereon.
